feat(hardening): M-Hard 1-5 — crypto, auth, rate limit, fingerprints, rotation
M-Hard 1: Cryptographic Hardening - constantTimeEqual, zeroize, randomUint32 on CryptoProvider - Fix Math.random() → crypto.randomUint32() for registrationId - Zero message keys and chain keys after use in ratchet.ts - Constant-time trust comparison in MemoryStorage + SQLiteStorage - Timing variance test catches early-exit regressions M-Hard 2: Self-Authenticated Prekey Server - Ed25519 signature verification on all write routes - signPayload/verifyPayload with canonical JSON, ±5 min replay window - Address validation (NFKC, alphanumeric + :_-.) - Global ShadeError → HTTP status mapping - ShadeFetchTransport signs requests when signingPrivateKey provided - Anonymous bundle fetches still allowed (read-only) M-Hard 3: Rate Limiting + DoS Protection - Token bucket rate limiter with pluggable store - Per-route limits: register 5/h/IP, fetch 60/min/IP, replenish 10/min/id - 64KB body size limit on POST - Retry-After header on 429 responses M-Hard 4: Auto-replenish + Fingerprints + Session Reset - Safety numbers (12 groups × 5 digits, Signal-style) - ensurePreKeyStock, resetSession, acceptIdentityChange - verifyRemoteIdentity for out-of-band comparison M-Hard 5: Identity Rotation with Grace Period - rotateIdentity archives old identity, generates fresh signed prekey - RetiredIdentity storage with addRetired/getRetired/pruneRetired - 7-day default grace period for decrypting old sessions - pruneExpiredIdentities for cleanup M-Hard 8: Error Hierarchy - New error types: Network, Storage, Validation, Timeout, RateLimit, Configuration, Unauthorized, Replay, IdentityRotation - All errors have stable SHADE_* codes - errorToHttpStatus for consistent HTTP mapping - toJSON() for network serialization 188 tests passing, zero failures.
