fix: replace JS-based actions with shell commands for Gitea compatibility

- Remove dtolnay/rust-toolchain (JS action) → use rustup via curl
- Remove Swatinem/rust-cache (JS action) → no replacement, builds from scratch
- All jobs now install Rust toolchain via shell commands
- Alpine job installs rustup directly with musl target support
- Ensures compatibility with Gitea Actions runners
