b77820534a feat(routing): pass-rate fetcher with TTL cache
HTTP client that calls GET /pass-rate?skill=X&window=Y on the brain pod.
Caches *float64 results (including nil) per-skill for the configured TTL
(default 60s). On non-200 or network error returns (nil, err) so the
upstream router can fall through to default-to-local.

db64ecb1d9 feat(routing): canonical request hash
SHA-256 of (system, user) joined with 0x00 separator, truncated to
uint64. Drives deterministic sample-band routing: identical prompt pair
→ same hash → same local-vs-Claude decision on every call.

ea29e5ebb8 feat(routing): decision policy
Pure-function Policy{Floor,Ceil} with Decide(*float64, uint64) Decision.
Rules in priority order: nil → local; ≥floor → local; <ceil → claude;
sample band → low bit of requestHash.
