[PR] ci(ci): label unlabelled issues with a model and check PR descriptions [iggy]

justinmclean opened a new pull request, #4554:
URL: https://github.com/apache/iggy/pull/4554

   ## Which issue does this PR address?
   
   N/A
   
   ## Rationale
   
   Issues opened blank, or with "Other / not sure" as the area, get no area label from the issue form, so a maintainer has to label them by hand. Contributor PRs often arrive without a linked issue or test notes, and reviewers have to ask for them.
   
   ## What changed?
   
   The issue labeller gets a fourth step. When the form gives no area, it asks a self-hosted model on ASF infrastructure (LLMAO, default `gemma4-26b`) for up to three area labels, plus `bug` or `enhancement` when the issue has no type label. Only exact matches to the existing allowlist are applied, so a prompt injection in the issue body can at worst pick a wrong label from that list. Without the `LLMAO_API_KEY` secret and `LLMAO_BASE_URL` variable the step does nothing, and model errors are warnings, not failures.
   
   A new PR Description check fails a contributor PR whose description has no linked issue (or explicit N/A), no description, or no test notes, and names each gap in the job summary. It is plain pattern matching, with no model, and skips bots, drafts and authors with write access.
   
   ## Local Execution
   
   - Passed: both scripts run under Node with mocked inputs. The labelling step was checked against a normal reply, a prompt injection, a think block, a prose reply, HTTP 503, a timeout and a missing key. The PR check passes 28 of the last 29 contributor PRs; the one it fails has no test notes. The unedited template fails all three checks.
   - Pre-commit hooks ran
   
   Not yet run against the live LLMAO endpoint, which needs the secret and variable set first.
   
   ## Setup (PMC member)
   
   1. Create an LLMAO personal key with Project set to Apache Iggy, then add it as a secret. The command prompts for the value, so the key never appears in shell history:
   
      ```bash
      gh secret set LLMAO_API_KEY -R apache/iggy
      ```
   
   2. Set the base URL from the LLMAO page, ending in `/v1`:
   
      ```bash
      gh variable set LLMAO_BASE_URL -R apache/iggy --body "https://<llmao-host>/v1"
      ```
   
   After merge I'll check the results on the next few issues and contributor PRs.
   
   ## AI Usage
   
   Claude Code wrote the workflow steps and the test harnesses. I reviewed the changes and the test results.

   @justinmclean could you extract the inline logic into standalone scripts, with the workflows calling the same code? Maintainers should be able to run them manually for a specific issue or PR. Please add `--dry-run` to the labeler so it prints the labels it would add without changing anything on GitHub, and include usage examples and the required configuration. This would make the logic easier to test, debug and maintain.

Review Comment:
   Checked it: with no token at all, `GET /repos/apache/iggy/pulls/4554` returns 200 and the full description, so the `contents: read` token is enough for a public repo.

   Converted to bash. scripts/ci/issue-labeler.sh and scripts/ci/pr-description-check.sh, using curl and jq. I ran them side by side with the Node versions on the same cases and got the same labels, output and exit codes.

Review Comment:
   Fixed. A `#123` now has to stand on its own, so `#007bff` and `&#123;` no longer count as an issue link. I kept the check across the whole body so a free-form description still passes, and the old and new versions gave the same result on the last 40 PRs.

Review Comment:
   No change here. apache/iggy has no `feature` label, so the template's `labels: ["feature"]` doesn't apply anything, and existing feature requests use `enhancement`, which is what the labeler offers.

   Done. The labeler and the PR check are now `scripts/ci/issue-labeler.mjs` and `scripts/ci/pr-description-check.mjs`, and the workflows run them. The labeler has `--dry-run`, and usage and configuration are in each script header and the PR description.

   @justinmclean i'm leaning towards having these scripts written in bash, because of 2 reasons:
   - consistency with rest of tooling
   - shellcheck is already in repo
   
   what do you think about that @justinmclean? i'm not 100% set in stone about this.

   @hubcio could you rerun the failed Swift e2e job? `userLifecycle()` got `transient_not_committed` wrapping the expected `unauthorized` error. This PR only changes CI scripts and workflows, so I think it's a flaky test.

Review Comment:
   critical: The workflow grants only `contents: read`, so the token has no `pull-requests` permission; `scripts/ci/pr-description-check.sh` calls `GET /repos/apache/iggy/pulls/{n}` with it and exits 1 on the 403. Add `pull-requests: read` to the permissions block.

Review Comment:
   simplification: The token header setup and curl status handling repeat `scripts/ci/issue-labeler.sh:124-149`. Move one request helper into `scripts/ci/lib/` and source it from both scripts.

Review Comment:
   warning: The labeler prints the model reply through `info` and `warning` at lines 245 and 250, so a reply line that starts with `::` runs as a workflow command. Replace `\r`, `\n` and `%` in model text before printing it.

Review Comment:
   warning: The issue check accepts `#\d+` anywhere, so a body with a hex color such as `#007bff` passes it with no linked issue. Require `Closes` or `Relates to`, or the repo issue URL, before the number.

Review Comment:
   nit: The prompt offers `enhancement`, but the feature template applies `feature` (`.github/ISSUE_TEMPLATE/feature_request.yml:20`). An issue without a type label therefore gets a different label from a templated feature request. Offer `feature` in the prompt and the reply filter.

   Thanks for the PR. It is labeled `S-waiting-on-review` and queued for review.
   
   Slash commands (own line, regular comment) move it around the queue:
   
   - `/ready` - back to `S-waiting-on-review` after addressing feedback
   - `/author` - flip to `S-waiting-on-author` while you finish changes
   - `/request-review @user-or-team` - request a reviewer
   - `/pin` - exempt the PR from the stale bot, `/unpin` to undo
   
   See [CONTRIBUTING.md](https://github.com/apache/iggy/blob/master/CONTRIBUTING.md#pr-triage-commands) for details.

Review Comment:
   Fixed. `info` and `warning` now keep each message on one line, and in Actions `warning` escapes `%`, CR and LF the way workflow commands expect, so model text can't start a line with `::`.
