fix: remove all systemd capability restrictions blocking package management

- Remove CapabilityBoundingSet and AmbientCapabilities (apt needs full root capabilities)
- Remove ReadWritePaths (unnecessary without ProtectSystem=strict)
- Fix E2E test: properly FAIL on status=failed package operations
- Fix E2E test: require status=completed for install/update/remove lifecycle
- Update dpkg packaging service file to match configs/
- Bump version to 0.3.5

+**Mistake:** Used ServerConfig::builder() which returns WantsVerifier state, then called with_protocol_versions() which requires WantsVersions state.
+**Correction:** Use ServerConfig::builder_with_provider(Arc::new(aws_lc_rs::default_provider())) to get WantsVersions state. Also need aws_lc_rs feature in Cargo.toml.

+## 2026-05-03 - RestrictSUIDSGID=true blocks sudo in systemd services
+**Mistake:** Service used RestrictSUIDSGID=true which prevented sudo from using setuid/setgid operations.
+**Correction:** Removed RestrictSUIDSGID=true from systemd service. Package management requires setuid/setgid for apt/dpkg.
+**Rule:** For package management services, do not use RestrictSUIDSGID=true. It blocks sudo and apt from working.
+**Status:** Active
+
+## 2026-05-03 - dpkg preinst creates linux-patch-api user causing permission issues
+**Mistake:** dpkg preinst script creates a linux-patch-api system user and changes directory ownership, causing the service to crash with 'Permission denied' on log file creation.
+**Correction:** Fix dpkg preinst to not create the linux-patch-api user or change directory ownership. Service runs as root and directories should be owned by root.
+**Rule:** For services that run as root, do not create a dedicated system user in the dpkg preinst script. Keep all directory ownership as root:root.
+**Status:** Active
+
+## 2026-05-03 - Service runs as root, no sudo needed for apt commands
+**Mistake:** Service used sudo to run apt commands even though it runs as root. This caused failures when systemd security restrictions blocked sudo.
+**Correction:** Removed sudo from apt command execution in the source code. Service runs as root and can execute apt directly.
+**Rule:** If a service runs as root, it does not need sudo to execute commands. Remove sudo from command execution.
+**Status:** Active
