versions_scanned for both the scanner and ILM collectors was read from
the Lifecycle work source's `checked` counter, which is never recorded on
the production scan path — so rustfs_scanner_versions_scanned_total and
rustfs_ilm_versions_scanned_total sat at zero even while objects_scanned
climbed. The two metrics also have distinct intended meanings that were
conflated: "versions scanned" (all versions, any bucket) vs "versions
checked for ILM actions" (lifecycle-configured buckets only).
Add a lifetime `versions_scanned` counter recorded for every version the
scanner walks (independent of ILM), and record the Lifecycle source's
`checked` counter from the ILM evaluator so the ILM metric reflects the
real checked subset. The scanner collector now reports total scanned
versions; the ILM collector keeps the ILM-checked subset.
Closes backlog#995 (OBS-09).

* fix(obs): isolate process sampler windows
Refs rustfs/backlog#1004
Refs rustfs/backlog#986
- add a reusable ProcessSampler so callers can own independent sysinfo refresh windows
- wire separate sampler instances for obs metrics scheduling and memory observability
- keep compatibility helpers while avoiding cross-task CPU and disk delta interference

* fix(obs): import process sampler bundle helper
Refs rustfs/backlog#1004
Refs rustfs/backlog#986
- import collect_process_metric_bundle_with in the metrics scheduler
- drop the stale collect_process_metric_bundle import after switching scheduler sampling to independent process samplers

* fix(obs): move process sampler into blocking task
Refs rustfs/backlog#1004
Refs rustfs/backlog#986
- move the memory observability process sampler into the spawn_blocking closure
- satisfy the closure static lifetime required by tokio while keeping the isolated sampler design intact

revert: restore #![allow(dead_code)] - clippy -D warnings treats warn as error
The #742 PR changed #![allow(dead_code)] to #![warn(dead_code)], but
CI runs clippy with -D warnings which turns warnings into errors.
This caused CI failures across multiple PRs.
Reverting to #![allow(dead_code)] until the dead code is actually
cleaned up. The 189 warnings in ecstore should be fixed incrementally
by deleting dead code and adding item-level allows, not by changing
the crate-level policy.
