perf(brain-retro): prompt-caching split on reviewer-agent
Add buildReviewPromptStructured() returning { system, user } and route
reviewViaDirectApi through callAnthropicAPI's structured branch — same
pattern the classifier already uses (router-classifier.mjs L456-484), so
infrastructure is reused, no new transport code.
system block: static instructions + 8-dim cues + schema-version notes
(byte-identical across episodes of the same schema_version → cache key
stable within a 5-min TTL).
user block: per-episode JSON (volatile).
Effect on Opus 4.7: ~zero until system grows past 4096-token cache-
minimum or model switches to Sonnet (2048 min). Anthropic silently
no-ops cache_control when prefix is below the minimum — no error,
cache_creation_input_tokens just stays at 0. Architecturally correct
and future-proof; activates the moment either condition flips.
buildReviewPrompt() kept as backward-compat wrapper.
Tests: +5 invariants for the split + cache-prerequisite check
(system identical across two v4 episodes with different bodies).
14/14 GREEN.
