fix(pr-status-sync): gh api --jq doesn't support jq's --arg flag

[octavianorg]

Summary

• Every PR opened/reopened event triggered a failure in the sync / open-pr job of pr-status-sync.yml with accepts 1 arg(s), received 4
• Root cause: gh api ... --jq --arg l "$BASE_LABEL" '...' — gh api --jq only accepts a single filter string; it has no --arg support like the standalone jq binary. The shell consumed --arg as the filter itself, leaving l, $BASE_LABEL, and the real filter as three stray positional args to gh api, which only accepts one (the endpoint)
• Fixed by fetching labels via gh api --jq '[.[].name]' and piping into a real jq -r --arg call — the same pattern already used correctly elsewhere in this file (the closed-PR path)

Test plan

• Reproduced the exact failure locally against a real PR with the old code
• Verified the fixed command runs cleanly against the same PR with no error
• Confirmed no other gh api --jq --arg occurrences exist elsewhere in this file/repo

Summary by CodeRabbit

• Bug Fixes
  • Improved PR status label cleanup to more reliably remove outdated base labels during pull request updates.
  • Reduced the chance of stale PR status information persisting after base changes.

📝 Walkthrough

Walkthrough

The PR status synchronization workflow now computes stale base labels with a two-stage jq pipeline: extracting label names first, then filtering them against BASE_LABEL.
