Pratik Mankawde 9adb6a255d test(telemetry): register the rotation spans and stall metrics with the harness ...

Adds `nodestore.rotate` and its eight phase children to expected_spans.json,
all `optional: true` because the 5-node localhost harness cluster never reaches
`online_delete`. Their parent-child relationships are asserted but skip-marked
so a run without a rotation stays green.

Adds `cache_metrics{metric="treenode_lock_hold_peak_us"|"fullbelow_lock_hold_peak_us"}`
to the asserted sync_diagnostics group -- both are observable and always emit,
even at zero. Puts `rotation_phase_duration_seconds` and `jobq_stall_total` in
`not_asserted.metrics_excluded`; both are workload-gated.

On the Cloud collector, adds an `ottl_condition` policy that keeps any trace
carrying a span whose name matches `^nodestore\.rotate`, so the 0.5% probabilistic
tail sampler cannot drop a rotation trace. Sampler is OR'd across policies.
