* feat(scanner): expose startup phases and attempt deadlines Share one node-local startup snapshot between native status and metrics. Track actual waits and first attempts without changing admission timing, coverage acknowledgement, or publication semantics.

Cover blocked recovery discovery and cancellation through the public entry.

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.
