Changes for version 0.02 - 2026-03-17
- New ops: add, update, swap, cas, pop, shift, drain, set_multi, get_multi, persist, set_ttl, touch, reserve, flush_expired_partial, ttl_remaining, stats, arena_used, arena_cap, stat_evictions, stat_expired, stat_recoveries
- Clock/second-chance eviction: lock-free LRU reads
- Hash-tag probe filtering, prefetch, lru_skip optimization
- SSE2-accelerated state scanning for iteration
- SSE2-accelerated tag matching in probe loops
- Inline small strings (≤7 bytes) stored in node structs, no arena overhead
- Batch get_multi with prefetch pipeline under single lock
- Fast monotonic clock (CLOCK_MONOTONIC_COARSE) for TTL paths
- Pre-sized copy_buf to avoid realloc on first access
- C-level sharding: new_sharded($path, $shards, ...) for parallel writes
- Cursor chains across shards with correct iterating/flush_deferred
- Harden header validation, fix cursor_seek gen tracking
- SHM_VERSION 7 (inline strings, monotonic timestamps)
