Andrew Stoltz 2b420ce8a4 runners: fleet-wide right-size CPU requests from 500m to 100m ...

All 33 runner Deployments now request 100m CPU instead of 500m,
freeing roughly 50 idle pods × 400m = ~20 cores back to the cluster.
Observed CPU usage on idle runners is ~1m via kubectl top; the 500m
request was a 500× over-provision that was eating allocatable CPU
and blocking new workload scheduling — WorldBuilder runner could not
be scheduled even at the new 100m request because the pre-existing
fleet held the cluster at 99% requested.

Burst headroom preserved by limits.cpu: 2000m unchanged. TtsReader
keeps its 8Gi memory limit from the 2026-05-25 OOMKill fix; only
the CPU request line moves.

Recreate strategy on each deployment means a brief offline window
per runner during rollout; in-flight CI jobs complete on the
existing container before the new spec takes effect.
