refactor(ui): update menu, selector for TTY detection; thin dispatcher

- Update menu.ts and selector.ts to use isStdinTTY() and function-based
  terminal colors
- Refactor index.ts from 995-line monolith to ~270-line dispatcher that
  registers all commands via the CLI parser and delegates to modules
- Add initTTY() call at startup for correct pipe/TTY detection
- Interactive menu expanded to include new commands (explain, review,
  changelog, suggest, amend)

+
+### Pull Request Flow
+
+`gai pr` detects the remote platform from `origin`:
+
+- GitHub remotes use the `gh` CLI
+- Gitea remotes use the `tea` CLI
+- GitLab remotes use the `glab` CLI
+- Unknown remotes prompt you to choose a platform
+
+The command compares your current branch against the default branch, pushes the branch if needed, generates a PR title/body from the branch commits and diff, then asks for confirmation before creating the PR.
