1b6a147579 feat(ai): add PI_CACHE_RETENTION env var for extended prompt caching
Adds support for extended cache retention via PI_CACHE_RETENTION=long:
- Anthropic: 5m -> 1h TTL
- OpenAI: in-memory -> 24h retention

Only applies to direct API calls (api.anthropic.com, api.openai.com).
Proxies and other providers are unaffected.

fixes #967
