feat: Waves 3-5 — FileStore, RAFT, JetStream clustering, and concurrency tests
Add comprehensive Go-parity test coverage across 3 subsystems: - FileStore: basic CRUD, limits, purge, recovery, subjects, encryption, compression, MemStore (161 tests, 24 skipped for not-yet-implemented) - RAFT: core types, wire format, election, log replication, snapshots (95 tests) - JetStream Clustering: meta controller, stream/consumer replica groups, concurrency stress tests (90 tests) Total: ~346 new test annotations across 17 files (+7,557 lines) Full suite: 2,606 passing, 0 failures, 27 skipped
