The sweep-cf-orphans workflow shipped in #2088 was noisier than
intended in two ways. This PR fixes both — was filed under the
Optional finding I left on the original review and now matters because
the noise is observably hitting the merge queue.
1) `merge_group: types: [checks_requested]` was firing the entire
sweep job on every PR through the merge queue. The original intent
("future required-check support without a workflow edit") never
materialized, and meanwhile every recent merge-queue eval (#2091,
#2092, #2093, #2094, #2095, #2097) generated a red `Sweep CF
orphans (merge_group)` run.
Drop the trigger. Comment in the workflow explains the re-add path
if/when the workflow IS wired as a required check (re-add the
trigger AND gate the actual sweep step with
`if: github.event_name != 'merge_group'` so merge-queue evals are
no-op success).
2) The `Verify required secrets present` step exits 2 when the 6
secrets aren't configured yet (the PR body's post-merge step,
still pending). That turns the hourly schedule into an hourly red
CI run for as long as the secrets stay unset.
Convert to a soft skip: emit a `:⚠️:` listing the missing
secrets and set a `skip=true` step output, then gate the sweep
step with `if: steps.verify.outputs.skip != 'true'`. Workflow
reports green and ops still sees the warning when they review
recent runs.
Net effect:
- merge-queue evals stop generating spurious red runs
- the schedule reports green-with-warning until secrets land
- once secrets land, behavior is identical to today's (real sweep
runs, hard-fails if a secret is later removed)
