feat: Switch from release-please to auto-release (#65)

Replace release-please with the auto-release pattern used by other CLIs:
- Add auto-release.yml to create tags automatically on push to main
- Add version.txt for base version (starting at 0.9)
- Remove release-please.yml and config files
- Update .goreleaser.yml to push to open-cli-collective/homebrew-tap
- Standardize secret name to TAP_GITHUB_TOKEN
