houseme 78d6918c52 feat: extend hotpath coverage across crates (#5505)
Add opt-in hotpath feature surfaces to every workspace crate and wire the root rustfs feature passthrough for function, allocation, and CPU profiling.

Add a focused set of function-level measurements for scanner, heal, lock, target replay, IAM, KMS, Keystone, trusted proxy, and capacity paths without adding request-scoped primitive wrappers.

RustFS Scanner

RustFS Scanner is the background maintenance scan loop. It handles usage accounting, lifecycle expiry and transition admission, bucket replication repair admission, scanner-driven heal/bitrot checks, and namespace alerts.

For operator-facing runtime controls, status fields, and tuning workflows, see Scanner Runtime Controls. For repeatable scanner-pressure validation, see Scanner Benchmark Runbook.

Chinese documentation is available in README.zh-CN.md.
