houseme 6cb47049e8 fix(obs): isolate process sampler windows (#4492)
* 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
