fix: replace git clone with curl+tar for act runner compatibility

The act runner images do not include git. Previous attempt used git clone
which failed with "git: command not found".

- Replace all git clone with curl downloading Gitea archive tarball
- Use tar to extract the archive into the working directory
- No dependency on git for checkout step
