* refactor(scanner): split scanner_folder item actions and ledger

Split the 6345-line scanner_folder.rs (46% inline tests) into a
canonical scanner_folder.rs + scanner_folder/ module tree with zero
behavior change:

- scanner_folder.rs (~2280): scan constants, alert cooldowns, metric
  accounting, resume ordering, tracing helpers, the FolderScanner
  struct with failed-object bookkeeping and the scan_folder traversal,
  and scan_data_folder
- scanner_folder/item_actions.rs (~890): CachedFolder, the get-size
  failure policy, ScannerItem with apply_actions and the heal/ILM
  admission helpers
- scanner_folder/ledger.rs (~280): the pending-scanner-heal ledger
  methods and their entry helpers (record/prune/clear-for-repaired/
  retry)
- scanner_folder/tests.rs (~2950): the inline test module as a child
  module

The ScannerItem path used by scanner_io resolves through a root
re-export, and every other crate path is unchanged. Cross-module items
gain pub(super), whose scope equals the old single-module privacy
domain. Code is moved verbatim apart from those markers, per-module
import headers, and rustfmt re-wraps.

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.
