Composite action that installs a Rust toolchain and caches cargo/crate dependencies.
Composite action that restores Rust build caches, installs a Rust toolchain, and saves updated cargo/rustup/target caches after the job.

### What it does
1. **Cache restore**Restores `~/.cargo/registry`, `~/.cargo/git`, `~/.rustup/toolchains`, and `target/` using Gitea's native `actions/cache`.
2. **Rust install** — Runs `rustup` to install or verify the requested toolchain.
3. **PATH setup** — Appends `$HOME/.cargo/bin` to `$GITHUB_PATH` so cargo/rustc are available in subsequent steps.
1. **Cache key**Hashes root/workspace `Cargo.toml`, `Cargo.lock`, and `rust-toolchain*` files without relying on `hashFiles()`.
2. **Cache restore/save** — Restores `~/.cargo/registry`, `~/.cargo/git`, `~/.rustup/toolchains`, and `target/` using Gitea's native `actions/cache`. The cache action saves updated paths in its post step after later build/test steps have populated them.
3. **Rust install** — Runs `rustup` with the minimal profile to install or verify the requested toolchain.
4. **PATH setup** — Appends `$HOME/.cargo/bin` to `$GITHUB_PATH` so cargo/rustc are available in subsequent steps.
### Cache key format
```
rust-linux-{hash(Cargo.lock)}{hash(Cargo.toml)}
{cache-prefix}-{runner.os}-{runner.arch}-{toolchain}-{hash(manifests/toolchain files)}
```
Warm builds run in ~4060s vs ~3min for a cold build.
