- Move src/agent/oauth/ to src/agent/providers/oauth/ (parent-child structure)
- Delete deprecated oauth/providers.ts re-export file
- Simplify Claude model names: claude-opus-4-5 (without date suffix)
- Update Codex models to current lineup (gpt-5.2, gpt-5.1-codex, etc.)
- Set claude-opus-4-5 as default model for claude-code provider

- Create src/agent/providers/ with registry.ts and resolver.ts
- registry.ts: Provider metadata, status checking, login instructions
- resolver.ts: API key resolution, model resolution
- oauth/providers.ts now re-exports from providers/ (deprecated)
- tools.ts: Remove PROVIDER_ALIAS and DEFAULT_MODELS (moved to providers/)
- Update imports in runner.ts and chat.ts
This separates concerns:
- oauth/ only handles OAuth credential reading
- providers/ manages all provider metadata and resolution
