Show the selected bot profile and add OpenRouter fallback (#18)

Uses Codex first, then Claude, then OpenCode through OpenRouter when quota is exhausted.

Every generated comment and review now identifies the selected profile and model in a final quote. The dependent action interface remains one master key.

Verified formatting, lint, type checks, encrypted profile decryption, current OpenCode CLI flags, and 45 tests.
