fix: resolve CI failures (fmt, clippy, tests)

- Fix rustfmt formatting in cache.rs, patches.rs, system.rs, routes.rs, main.rs - Add Default impl for PackageCacheState (clippy new_without_default) - Change apply_with_cache_retry generic bound from Fn to FnMut - Add mut to refresh_fn parameter for FnMut compatibility - Replace bool comparison with ! operator (clippy bool_comparison) - Update todo.md with completed status
fix: add package cache refresh before apply and on health check

+## Package Cache Management
+
+### Module: `src/packages/cache.rs`
+
+The package cache module manages the local package index state, ensuring that package metadata is current before performing operations.
+
+**Key Components:**
+- `PackageCacheState` - Thread-safe in-memory cache state with Mutex protection
+- `PackageCacheStatus` - Snapshot of cache state for reporting
+- `CacheStateFile` - Persistent state format for serialization
+- `is_fetch_error()` - Detects 404/fetch errors for automatic retry
+- `apply_with_cache_retry()` - Generic retry wrapper for cache-related failures
+- `run_command_with_timeout()` - Executes cache refresh commands with timeout
+
+**State Persistence:**
+- Cache state persists to `/var/lib/linux_patch_api/state/cache.json`
+- State is loaded on service startup and saved after every update
+- Persists `last_cache_update` timestamp and `last_update_success` flag
+- Parent directory is auto-created if missing
+
+**Stale Detection:**
+- Cache is considered stale after 4 hours (`STALE_THRESHOLD_SECS = 14400`)
+- Health check automatically refreshes stale cache
+- Patch apply operations always refresh cache before proceeding (mandatory)
+
+**Refresh-Before-Apply Flow:**
+1. `POST /patches/apply` creates a job and spawns background task
+2. Background task refreshes package cache (mandatory, not configurable)
+3. If refresh fails: job fails immediately with error message
+4. If refresh succeeds: job progresses to 10%, applies patches
+5. If apply fails with 404/fetch error: refresh cache and retry once
+6. If retry also fails: job fails with error
+
+**Cache Refresh Timeout:** 120 seconds (`CACHE_REFRESH_TIMEOUT_SECS`)

+# Issue #2: Package Cache Refresh - Spec Document
+
+**Version:** 1.1.17  
+**Date:** 2026-05-27  
+**Status:** Approved  
+**Gitea Issue:** https://gitea-lxc.moon-dragon.us/git-echo/linux_patch_api/issues/2
+
+---
+
+## Problem Statement
+
+On 2026-05-27, `dashboard.moon-dragon.us` (Ubuntu 24.04.2 LTS, agent v1.1.16) had 11 pending patches but ALL `patch_apply` jobs failed with 404 errors. Root cause: stale `apt` package cache referencing superseded versions no longer in upstream repos.
+
+**Impact:** 700/757 total jobs failed (92.5% failure rate) across all managed hosts.
+
+---
+
+## Requirements (from Issue #2)
+
+| # | Requirement | Priority | Description |
+|---|-------------|----------|-------------|
+| 1 | Pre-Upgrade Cache Refresh | **MUST** | Run package index update before every `patch_apply` operation |
+| 2 | Regular Interval Cache Refresh | **MUST** | Refresh package index on each health check (manager-triggered) |
+| 3 | 404/Fetch Error Handling | **SHOULD** | Auto-retry with cache refresh on 404 errors, then report failure |
+| 4 | Stale Cache Detection | **SHOULD** | Track `last_cache_update` timestamp; include in health response |
+
+---
+
+## Architecture Decisions (Kelly-Approved)
+
+1. **New module:** `src/packages/cache.rs` for dedicated cache management
+2. **Health check integration:** Cache refresh triggered by health check from manager
+3. **Force cache refresh before apply:** Always on, NOT configurable
+4. **Cache interval:** Controlled by manager health check frequency, not agent config
+5. **Health check reports `last_cache_update`:** If cache refresh fails, health check returns degraded
+6. **OS detection:** Already exists via compile-time backend selection
+7. **Version bump:** 1.1.17
+8. **Health check failure mode:** HTTP 200 with `status: "degraded"` (not 503)
+9. **Cache refresh timeout:** 120 seconds
+10. **404 retry count:** Hardcoded 1 retry (not configurable)
+11. **Cache state persistence:** State file at `/var/lib/linux_patch_api/state/cache.json`; in-memory otherwise

+
+## Design Specification
+
+### 1. New Module: `src/packages/cache.rs`
+
+#### `PackageCacheStatus` struct
+
+```rust
+pub struct PackageCacheStatus {
+    pub last_update: Option<DateTime<Utc>>,
+    pub last_update_success: bool,
+    pub last_update_error: Option<String>,
+}
+```
+
+#### `PackageCacheRefresher` trait
+
+```rust
+pub trait PackageCacheRefresher: Send + Sync {
+    /// Refresh the package index (apt update, dnf check-update, etc.)
+    fn refresh_cache(&self) -> Result<()>;
+    
+    /// Get the current cache status
+    fn cache_status(&self) -> PackageCacheStatus;
+    
+    /// Check if cache is stale (older than threshold)
+    fn is_cache_stale(&self, threshold: Duration) -> bool;
+}
+```
+
+#### Per-Backend Refresh Commands
+
+| Backend | Refresh Command | Notes |
+|---------|----------------|-------|
+| AptBackend | `apt-get update` | Full index refresh |
+| DnfBackend | `dnf check-update --refresh` | Force metadata refresh |
+| YumBackend | `yum makecache` | Rebuild metadata cache |
+| ApkBackend | `apk update` | Update repository index |
+| PacmanBackend | `pacman -Sy` | Sync databases (with caution note) |
+
+### 2. Health Check Enhancement: `src/api/handlers/system.rs`
+
+#### New `HealthData` response
+
+```rust
+pub struct HealthData {
+    pub status: String,           // "healthy" or "degraded"
+    pub uptime_seconds: u64,
+    pub version: String,
+    pub last_cache_update: Option<String>,  // RFC3339 timestamp
+    pub cache_status: String,     // "fresh", "stale", "unknown", "failed"
+}
+```
+
+#### Health check flow
+
+```
+GET /health or GET /api/v1/health
+  │
+  ├─ Read uptime (existing)
+  ├─ Read version (existing)
+  ├─ Call backend.cache_status() → PackageCacheStatus
+  │
+  ├─ If cache is stale (>4 hours) OR never refreshed:
+  │   ├─ Call backend.refresh_cache()  (120s timeout)
+  │   ├─ If success: last_cache_update = now, cache_status = "fresh"
+  │   └─ If failure: status = "degraded", cache_status = "failed"
+  │
+  └─ Return HealthData (HTTP 200 always)
+```
+
+**Key rule:** If cache refresh is attempted and fails, health check returns HTTP 200 with `status: "degraded"`. The manager decides how to handle degraded status.
+
+### 3. Pre-Apply Cache Refresh: `src/api/handlers/patches.rs`
+
+#### Patch apply flow change
+
+```
+POST /api/v1/patches/apply
+  │
+  ├─ Create job (existing)
+  ├─ Return 202 Accepted (existing)
+  │
+  └─ Background task:
+      ├─ job_manager.update_job(Running, 0%, "Refreshing package index...")
+      ├─ backend.refresh_package_cache()  ← NEW: Always runs before apply (120s timeout)
+      │   ├─ If failure: job_manager.fail_job("Package cache refresh failed: ...")
+      │   └─ If success: continue
+      ├─ job_manager.update_job(Running, 10%, "Cache refreshed, applying patches...")
+      ├─ backend.apply_patches(packages)  (existing)
+      └─ ... (existing completion flow)
+```
+
+**Key rule:** Cache refresh before apply is MANDATORY and NOT configurable. If it fails, the patch_apply job fails immediately with a clear error message.
+
+### 4. 404/Fetch Error Retry Logic
+
+#### In `src/packages/cache.rs`
+
+```rust
+/// Execute a patch operation with automatic cache refresh on 404/fetch errors
+/// Hardcoded 1 retry after cache refresh on fetch errors.
+pub fn apply_with_cache_retry<F>(
+    backend: &dyn PackageManagerBackend,
+    apply_fn: F,
+) -> Result<()>
+where
+    F: Fn() -> Result<()>,
+{
+    match apply_fn() {
+        Ok(()) => Ok(()),
+        Err(e) if is_fetch_error(&e) => {
+            // Refresh cache and retry once
+            backend.refresh_package_cache()?;
+            apply_fn()
+        }
+        Err(e) => Err(e),
+    }
+}
+
+/// Check if error is a fetch/404 error that warrants cache refresh retry
+fn is_fetch_error(error: &anyhow::Error) -> bool {
+    let msg = error.to_string().to_lowercase();
+    msg.contains("404") 
+        || msg.contains("not found") 
+        || msg.contains("failed to fetch")
+        || msg.contains("unable to fetch")
+}
+```
+
+**Retry policy:** Hardcoded 1 retry after cache refresh on 404/fetch errors. If retry also fails, report failure with specific error.
+
+### 5. Stale Cache Detection
+
+#### In `src/packages/cache.rs`
+
+- Track `last_cache_update: Option<DateTime<Utc>>` in a thread-safe `Arc<Mutex<PackageCacheState>>`
+- `is_cache_stale(threshold)` returns `true` if:
+  - `last_cache_update` is `None` (never refreshed)
+  - `last_cache_update` is older than threshold (default: 4 hours)
+- Used by health check to decide whether to trigger refresh
+- Used by patch_apply to log warning (but still force-refresh regardless)
+
+### 6. PackageManagerBackend Trait Extension
+
+```rust
+pub trait PackageManagerBackend: Send + Sync {
+    // ... existing methods ...
+    
+    /// NEW: Refresh the local package index
+    fn refresh_package_cache(&self) -> Result<()>;
+    
+    /// NEW: Get the last cache update timestamp
+    fn last_cache_update(&self) -> Option<DateTime<Utc>>;
+}
+```
+
+Each backend implements `refresh_package_cache()` using its OS-specific command.
+
+### 7. Cache State Persistence
+
+The `last_cache_update` timestamp persists to disk at `/var/lib/linux_patch_api/state/cache.json`:
+
+```json
+{
+  "last_cache_update": "2026-05-27T13:00:00Z",
+  "last_update_success": true
+}
+```
+
+- Written after each successful or failed cache refresh
+- Read on service startup to initialize in-memory state
+- If file is missing or corrupt, treated as never-refreshed (triggers refresh on first health check)
+- File permissions: 644 (readable by manager for diagnostics)
+
+### 8. Configuration Changes
+
+**No new configuration parameters.** Per Kelly's decision:
+- Cache refresh before apply is always-on (not configurable)
+- Cache refresh interval is controlled by manager health check frequency
+- Stale threshold is hardcoded at 4 hours
+- Cache refresh timeout is hardcoded at 120 seconds

+
+## Implementation Order
+
+1. **`src/packages/cache.rs`** - Core cache types, stale detection, state persistence
+2. **Backend implementations** - Add `refresh_package_cache()` and `last_cache_update()` to each backend in `mod.rs`
+3. **Health check enhancement** - Update `system.rs` to include cache status and trigger refresh
+4. **Pre-apply refresh** - Update `patches.rs` job flow to refresh before apply
+5. **404 retry logic** - Add retry wrapper in `cache.rs`
+6. **Version bump** - Update `Cargo.toml` to 1.1.17
+7. **Documentation** - Update `ARCHITECTURE.md` and `REQUIREMENTS.md`
+8. **State persistence** - Implement cache.json read/write in `cache.rs`
+9. **Tests** - Unit tests for cache logic, integration tests for health check
+
+---
+
+## Test Plan
+
+### Unit Tests
+- `cache_status()` returns correct initial state
+- `is_cache_stale()` returns true for never-refreshed and >4h old
+- `is_fetch_error()` correctly identifies 404/fetch errors
+- `apply_with_cache_retry()` retries once on 404 then fails on second attempt
+- Each backend's `refresh_package_cache()` calls correct command
+- State file read/write works correctly
+- Corrupt/missing state file handled gracefully
+
+### Integration Tests
+- `GET /health` returns `last_cache_update` and `cache_status` fields
+- `GET /health` triggers cache refresh when stale
+- `GET /health` returns `"degraded"` when cache refresh fails (HTTP 200)
+- `POST /api/v1/patches/apply` refreshes cache before applying
+- `POST /api/v1/patches/apply` fails job when cache refresh fails
+- 404 retry logic works end-to-end
+- State persists across service restart
