Remove every bare `#[allow(dead_code)]` in io-core, object-capacity, targets, rio, and scanner. Each allow was stripped first and clippy was then asked which ones the compiler actually missed, so the verdicts rest on the diagnostic rather than on inspection. 23 were inert: they sat on `pub fn`s inside `pub mod`s, where `dead_code` does not apply, or on scanner integration-test helpers that the tests in the same file do call. The remaining 3 are in rio's private `compress_index` module and the code behind them is deleted rather than annotated. `remove_index_headers` is dead and also wrong — after skipping the 4-byte chunk header it matches against `S2_INDEX_TRAILER` where `S2_INDEX_HEADER` sits, so it returns `None` for every well-formed index; rio-v2 carries the correct equivalent that is actually in use. `restore_index_headers` is its unreachable counterpart, likewise duplicated live in rio-v2. `Index::reset` is a private method with no caller.

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.
