feat: update provider model catalog (#143)

## Summary
- Updates Anthropic catalog to Claude Sonnet 5 and Claude Opus 5.
- Updates OpenAI catalog to GPT-5.6 Sol and GPT-5.6 Terra.
- Keeps DeepSeek V4 Pro, promotes Sonnet 5 as default, and uses Terra as
fallback.
- Updates product self-knowledge so the agent-visible catalog matches
the UI.

## Decisions
- Preserve DeepSeek V4 Pro unchanged because it is already implemented
and live-validated.
- Keep provider-prefixed logical IDs as the single source of truth.
- Reconcile active old model selections to Sonnet 5 while preserving
historical run provenance.

## Test Plan
- [x] Skill bundle
- [x] Typecheck
- [x] Lint
- [x] Full production build
- [x] Worker dry-runs
- [x] Local model picker verification
- [x] Local DeepSeek V4 Pro end-to-end UI run and routing-log
verification
- [ ] Production model picker verification
- [ ] Production Anthropic/OpenAI keyed inference

 Cheatcode accepts provider-prefixed OpenRouter model IDs even though OpenRouter is not shown as a separate catalog row. Google AI keys are tool-only credentials for image/video generation and browser automation; agent runs reject `google/<model-id>` selections. BYOK keys are configured in Models and decrypted only for the active request or tool invocation. Supported provider key families are Anthropic, OpenAI, Google AI, OpenRouter, DeepSeek, Exa, and Firecrawl. BYOK key counts are not limited by subscription-plan slots.
