test: add comprehensive tests for Marmot Phase 2 components
38 test cases covering:
- ChaCha20Poly1305: RFC 8439 §2.8.2 test vector, round-trip, tamper
detection, wrong key, invalid nonce/key length, large messages
- GroupEventEncryption: round-trip, empty/large messages, format
validation, random nonce uniqueness, tamper detection, integration
with GroupEvent.build()
- CommitOrdering: deterministic winner selection (lowest created_at,
smallest id tiebreak), comparator sorting, EpochCommitTracker
lifecycle (add/resolve/clear)
- KeyPackageUtils: validation (encoding, content, ref), selection
policy (prefer non-last-resort, newest), migration kind detection
- MarmotFilters: all filter builders produce correct kinds, tags,
authors, since parameters; no empty filters
