Updates the timelord action to fall back to git-warp-time when the cache is completely empty, enabling timestamp restoration even on fresh builds.

When git-warp-time is used, performs an unshallow fetch to get full history, while subsequent runs use normal fetches. Simplifies the interface by making inputs optional with sensible defaults.

Adds binary caching for timelord-cli and git-warp-time tools to avoid repeated installations, and updates paths to use /usr/share/rust/.cargo/bin/ for the catthehacker runner image used by the dind profile (may need updating if/when switching to standard image).

The main timelord restore now happens inside the Dockerfile itself, as Docker intentionally wipes all file mtimes on COPY/ADD operations.
