docs: fix stale status-conditions.md reference in AGENTS.md (#309)

The 'Adding a new operator feature' checklist referenced
docs/reference/status-conditions.md, which does not exist. Status
conditions are documented in docs/reference/configuration.md under
the 'Status Conditions' section. Updated the checklist to point to
the correct location.
