fix(cache-warming): accurate cache rate + expectedCacheRate (retention) metric
The Claude cache % read 100% whenever anything was cached, because the metric's
denominator (inputTokens) excluded cached tokens on Anthropic. Fixed upstream in
../claude/provider-anthropic (inputTokens = total prompt); this commit adds the
companion retention metric and exposes it:
- transport-contract: WarmResponse += expectedCacheRate
- transport-http: POST /chat/warm returns expectedCacheRate = cacheRead/(cacheRead+cacheWrite)
- cache-warming: computeExpectedCacheRate + a per-conversation 'cache retention' surface stat
- handoff: documents the fix + cache-rate vs expected-cache (cross-turn) for the FE
Live-verified vs claude haiku: real turn cache rate 61% (was inflated 100%);
warm within TTL expectedCacheRate=100%, after expiry=0%.
