gitch 이전 버전 및 전체 버전

## Highlights
• Profiles now separate the profile id from the Git author name with `git_name`.
• Switching defaults to repo-local Git config inside a repository and all switch paths now share one apply flow.
• SSH selection is deterministic through `core.sshCommand`, not just best-effort `ssh-agent` loading.
• Hooks are repo-local by default, shell integrations auto-switch on directory change, and the VS Code extension is repo-aware.

## Quality
• `gitch status` is read-only unless `--auto-switch` is requested.
• Active-profile detection now checks the full applied profile instead of matching on email alone.
• macOS directory-rule matching now handles symlinked path aliases correctly.
• CI now covers the Go CLI and the VS Code extension test/compile path.

## Availability
• GitHub release assets are published for macOS, Linux, and Windows.
• Homebrew tap has been updated to `2.3.0`.
• VS Code extension `2.3.0` has been published.

## Verification
• `go test ./...`
• `go build ./...`
• `npm test`
• `npm run compile`
