ci(autofix): loosen issue candidate filters so the agent finds work (#5860)

* ci(autofix): loosen issue candidate filters so the agent finds work

The scheduled issue phase had been finding 0 candidates on every run. Tier-1
requires the rarely-applied status/ready-for-agent label, and tier-2's
"unattended = no human comment at all" rule fought its ">2 days old" age
gate: on a busy repo every aged bug already has a community reply, so the
funnel collapsed (128 aged bugs -> 0 survivors) purely on the comment rule.

- Unattended now keys off maintainer engagement (OWNER/MEMBER/COLLABORATOR
  comments, excluding our own bots), not any human comment. Community
  "+1"/"me too" no longer disqualifies an issue.
- Tier-1 and tier-2 are always both gathered (tier-1 prioritized, then
  de-duped by number) so a single weak ready-for-agent issue can't starve
  the run.
- Tier-2 scans a bounded age window via MIN_ISSUE_AGE_DAYS..MAX_ISSUE_AGE_DAYS
  (1..15) to focus on fresh, settled bugs instead of an unbounded set.

* test(ci): cover autofix tier merge guards

* test(ci): cover autofix unattended filter

* fix(ci): summarize autofix comment refresh drops

* fix(ci): bound autofix tier-2 comment-refresh API calls

Cap the tier-2 issues fed into the comment-refresh loop to 15 (a margin
above the ~10 ever selected, since filter_unattended_candidates drops
attended issues afterward) and request full pages with per_page=100, to
avoid GitHub secondary rate limits. Add workflow tests asserting the
forced-issue skip/in-progress exclusion and the tier-2 ready-for-agent
label exclusion stay in place.

* fix(ci): refresh all scanned tier-2 autofix issues, not just first 15

The previous change capped comment-refresh to the first 15 tier-2 issues
before filter_unattended_candidates runs. The scan still fetches 30, so
valid unattended bugs at positions 16-30 were never refreshed nor
filterable: if the first 15 were all maintainer-attended/dropped, the run
could end with zero candidates again — the failure this PR set out to fix.

Drop the .[0:15] refresh cap and refresh the full scanned set (already
bounded by --limit 30 on the scan). per_page=100 stays as the
pages-per-issue rate-limit mitigation, and the drop summary total/counters
reflect the full refreshed set again. Top-N selection after filtering is
unchanged.

* fix(ci): order tier priority before recency in autofix assess prompt

The assess prompt gave two conflicting selection rules: the tier note says not to pick a tier-2 issue over a comparably actionable tier-1 one, while the recency tiebreaker says to prefer the most recently reported. Since tier-1 has no age bound and tier-2 is the recent (1-15 day) tier, these point in opposite directions for comparable confidence. Make recency apply only after the tier preference and only within the same tier, removing the contradiction. Prompt text only; no shell/jq change.

* fix(ci): guard forced-issue jq and derive autofix comment scratch path

Address two review suggestions on the autofix candidate scan step.

- Wrap the forced-issue candidate jq in the same error guard the other
  jq calls use (tier-1/tier-2 stamp, tier merge): on malformed
  forced-issue JSON it now emits a ::warning:: and falls back to an empty
  candidate list instead of silently producing an empty candidates.json
  with no diagnostic.
- Make refresh_issue_comments reuse-safe by deriving its NDJSON scratch
  path from the output_file parameter (${output_file%.json}.ndjson)
  instead of hardcoding tier2-with-comments.ndjson, so a second call or a
  different tier can't clobber a shared scratch file. Behavior for the
  current single call is unchanged.
