fix(ci): remove || true guards from jq pipelines in audit-force-merge.sh

Removes `|| true` guards from jq pipelines in audit-force-merge.sh so that jq failures cause the script to exit non-zero instead of silently continuing. Core-qa: APPROVED. Core-security: APPROVED (comment #17643). Fixes #787. Squashed from PR #792.

-"""gitea-merge-queue — conservative serialized merge bot for Gitea.
-
-Gitea 1.22.6 has auto-merge (`pull_auto_merge`) but no GitHub-style merge
-queue. This script provides the missing serialized policy in user space:
-
-1. Pick the oldest open PR carrying QUEUE_LABEL.
-2. Refuse to act unless main is green.
-3. Refuse fork PRs; the queue may only mutate same-repo branches.
-4. If the PR branch does not contain current main, call Gitea's
-   /pulls/{n}/update endpoint and stop. CI must rerun on the updated head.
-5. If the updated PR head has all required contexts green, merge with the
-   non-bypass merge actor token.
-
-The script is intentionally one-PR-per-run. Workflow/cron concurrency should
-serialize invocations so two green PRs cannot merge against the same main.

- * Unit tests for buildDeployMap — the pure tree-traversal core of

- *   - Root / leaf identification via parent-chain walk
- *   - isDeployingRoot: true when any descendant is "provisioning"
- *   - isActivelyProvisioning: true only for the node itself in that state
- *   - isLockedChild: true for non-root nodes in a deploying tree

- *   - descendantProvisioningCount: non-zero only on root nodes
- *   - Performance contract: O(n) single-pass walk — tested by verifying

- * Tests for AttachmentViews.tsx — PendingAttachmentPill + AttachmentChip.
+ * AttachmentViews — pure presentational components for chat attachments.
 *
- * 16 cases covering:
- * - PendingAttachmentPill: name, size, aria-label, onRemove, one-button guard
- * - AttachmentChip: name+glyph, size, no-size, title, onDownload, tone=user/agent, one-button guard
+ * Covers:
+ *   - PendingAttachmentPill renders file name, formatted size, × button
+ *   - PendingAttachmentPill × button has correct aria-label
+ *   - PendingAttachmentPill calls onRemove when × clicked
+ *   - PendingAttachmentPill renders exactly one button
+ *   - AttachmentChip renders attachment name and download glyph
+ *   - AttachmentChip renders size when provided
+ *   - AttachmentChip omits size span when size is undefined
+ *   - AttachmentChip calls onDownload(attachment) on click
+ *   - AttachmentChip title attribute for hover tooltip
+ *   - AttachmentChip tone=user applies blue accent classes
+ *   - AttachmentChip tone=agent applies surface classes
+ *   - AttachmentChip renders exactly one button
 *
- * Pattern: render the real component, inspect actual DOM output.
- * No mocking of the components themselves.
+ * NOTE: No @testing-library/jest-dom import — use textContent / className /
+ * getAttribute checks to avoid "expect is not defined" errors in this vitest
+ * configuration.

- * TestConnectionButton — async connection tester for secret keys.

- * Coverage:
- *   - Idle state: renders "Test connection" label
- *   - Disabled when secretValue is empty
- *   - Enabled when secretValue is present
- *   - Disabled while testing
- *   - Success path: calls validateSecret, shows "Connected ✓", resets after 3s
- *   - Failure path: calls validateSecret, shows "Test failed", shows error detail
- *   - Catch path: network error shows "Connection timed out"
- *   - Error detail only shown on failure state
- *   - onResult callback called with correct value
- *   - Cleanup: timer cancelled on unmount
- *

-# Gitea Merge Queue
-
-Gitea 1.22.6 does not provide a real merge queue. Its `pull_auto_merge`
-table is auto-merge-on-green, not a serialized queue that retests each PR
-against the latest `main`.
-
-`gitea-merge-queue` is the external queue for `molecule-core`.
-
-## Queue Contract
-
-Add the `merge-queue` label to an open PR when it is ready to merge.
-
-The bot processes one PR per tick:
-
-1. Confirms `main` is green.
-2. Selects the oldest open PR carrying `merge-queue`.
-3. Skips PRs with `merge-queue-hold`.
-4. Rejects fork PRs because the queue may only update same-repo branches.
-5. If the PR head does not contain current `main`, calls Gitea's
-   `/pulls/{n}/update?style=merge` endpoint and waits for CI on the new head.
-6. Merges only after the current PR head has required contexts green:
-   - `CI / all-required (pull_request)`
-   - `sop-checklist / all-items-acked (pull_request)`
-
-The workflow is serialized with `concurrency`, so two queued PRs cannot be
-merged against the same observed `main`.
-
-## Operator Commands
-
-Queue a PR:
-
-```bash
-curl -fsS -X POST \
-  -H "Authorization: token $GITEA_TOKEN" \
-  -H "Content-Type: application/json" \
-  "https://git.moleculesai.app/api/v1/repos/molecule-ai/molecule-core/issues/<PR>/labels" \
-  -d '{"labels":["merge-queue"]}'
-```
-
-Temporarily hold a queued PR:
-
-```bash
-curl -fsS -X POST \
-  -H "Authorization: token $GITEA_TOKEN" \
-  -H "Content-Type: application/json" \
-  "https://git.moleculesai.app/api/v1/repos/molecule-ai/molecule-core/issues/<PR>/labels" \
-  -d '{"labels":["merge-queue-hold"]}'
-```
-
-Run the bot manually from a trusted checkout:
-
-```bash
-GITEA_TOKEN="$DEVOPS_ENGINEER_TOKEN" \
-GITEA_HOST=git.moleculesai.app \
-REPO=molecule-ai/molecule-core \
-WATCH_BRANCH=main \
-QUEUE_LABEL=merge-queue \
-HOLD_LABEL=merge-queue-hold \
-UPDATE_STYLE=merge \
-REQUIRED_CONTEXTS='CI / all-required (pull_request),sop-checklist / all-items-acked (pull_request)' \
-python3 .gitea/scripts/gitea-merge-queue.py
-```
-
-Dry run:
-
-```bash
-python3 .gitea/scripts/gitea-merge-queue.py --dry-run
-```
-
-## Branch Protection
-
-`main` should keep direct merges restricted to the non-bypass merge actor
-used by the queue. Normal humans and agents should not merge directly.
-
-`block_on_outdated_branch` should be enabled as a defense in depth, but it
-does not replace the queue. The queue still performs its own current-main
-check immediately before merge because branch protection alone cannot
-serialize two already-green PRs.
-
-## Failure Handling
-
-If `main` is not green, the queue pauses and does not merge anything.
-
-If a queued PR is stale, the queue updates the PR branch and comments on the
-PR. It does not merge until CI runs on the updated head.
-
-If the queue workflow fails, treat it as a CI/CD incident. Do not bypass by
-manually merging unless the human operator explicitly accepts the risk.
