5 people 114bb4acec perf(ecstore): add bucket existence cache and allocator feature flags (#6496) ...

## Bucket existence cache
- Add BucketExistenceCache in crates/ecstore/src/disk/fs.rs
- Cache bucket directory existence checks with 60s TTL
- Replace access() calls with cached_access() in local.rs
- Add invalidate_bucket_cache() for cache invalidation on create/delete
- Reduces statx syscalls by 89% (from 10,716/s to 1,186/s)

## Allocator feature flags
- Add mimalloc and jemalloc features to rustfs/Cargo.toml
- Default: system allocator (Rust built-in)
- --features mimalloc: mimalloc allocator
- --features jemalloc: jemalloc allocator
- Allows A/B testing different allocators

## Performance impact
- 1KiB PUT: 861 obj/s (unchanged, futex is main bottleneck)
- statx reduction: 89% (from 10,716/s to 1,186/s)
- Main bottleneck remains mimalloc internal synchronization
