The supervisor now supports routing an organization's runs to specific
nodes. `KUBERNETES_ORG_PLACEMENT_OVERRIDES` takes JSON keyed by the
internal org ID, adding node selector entries and tolerations to that
org's run pods, e.g. to route an org onto a dedicated, tainted node
pool:
```json
{"<orgId>": {"nodeSelector": {"pool": "dedicated"}, "tolerations": "dedicated=runs:NoSchedule"}}
```
The node selector merges over the defaults (the override wins on key
collision, with a warning logged). Tolerations append to the existing
runner and scheduled-run sets. Overrides are validated at startup
similar to `KUBERNETES_RUNNER_TOLERATIONS`.
Exposed in the Helm chart as
`supervisor.config.kubernetes.orgPlacementOverrides`, where tolerations
can also be given as a list.
