perf(cache): add reference counting to reduce GC pressure

Add reference counting to Block struct so evicted cache blocks
return their buffers to the pool immediately instead of waiting
for GC. This reduces garbage creation by ~33% under cache pressure.

Changes:
- Add IncRef/DecRef methods to Block with atomic refcount
- Cache.Get increments refcount for caller
- Cache eviction/removal calls DecRef to release reference
- Readers properly DecRef blocks when done
- Remove fromCache tracking (no longer needed)
