* feat(runtime): add weighted workload scheduler
Signed-off-by: discord9 <55937128+discord9@users.noreply.github.com>
* feat(runtime): switch catio to GreptimeTeam fork with admission-wait metrics
Use the GreptimeTeam/catio fork (pinned c20eafc) which adds
ClassStats::total_admission_wait and ClassStats::admitted, recorded
at each QUEUED -> ADMITTED transition. This exposes the scheduler's
own admission delay (excluding Tokio queueing and poll execution),
enabling admission-wait based fairness gates.

* chore: bump catio to dynamic-config revision
Bump the catio scheduler fork to 9f4b028 which adds
Scheduler::set_weight and Scheduler::set_max_concurrent_polls for
runtime configuration.

* feat(perf): runtime-adjustable workload scheduler parameters
Expose dynamic adjustment of the experimental workload scheduler at
runtime:
- common-runtime: set_workload_scheduler_weights and
set_workload_scheduler_max_concurrent_polls, which forward to the
catio scheduler's set_weight/set_max_concurrent_polls when the
scheduler is enabled and reject zero values.
- servers: /debug/workload_scheduler/weights and
/debug/workload_scheduler/max_concurrent_polls POST handlers, so
operators can rebalance query/write shares or admission concurrency
without restarting the datanode.
Both endpoints return 400 with a clear reason when the scheduler is
disabled or the requested value is invalid.

* feat(perf): add GET /debug/workload_scheduler status endpoint
Returns the current weights (per class), max_concurrent_polls,
active_polls and per-class counters (queued, tasks, wakes, polls,
completed, cancelled, admitted, total_admission_wait) as JSON. When the
scheduler is disabled, returns enabled=false with the other fields
omitted, so operators can distinguish 'disabled' from an error.

* chore: bump catio to time-accounting revision
Bump the catio scheduler fork to 257ba56 which replaces
admission-count accounting with real execution-time accounting
(pass += exec_time / (weight * concurrency)), so CPU share follows the
configured weights regardless of poll length.

* chore: bump catio to lock-free sampling revision
Bump the catio scheduler fork to efdc0a4 which adds an optional
downsampled clock sampling mode (SchedulerBuilder::sample_every_polls,
default off) with a lock-free per-class atomic counter, so the
downsampled path costs one fetch_add per poll instead of a global
mutex.
