test(canvas): add FilesTab tree + component coverage — 36 cases

Add tree.test.ts (25 cases): buildTree and getIcon pure functions from
FilesTab/tree.ts. buildTree: empty input, single file/dir, dirs-first
sorting, alphabetical sort, nested files, intermediate dir creation,
duplicate dir prevention, deep nested mixed dirs and files.
getIcon: all 9 file-type extensions, case-insensitive, default fallback.

Add FilesTab.test.tsx (11 cases): FilesTab/PlatformOwnedFilesTab component
tests — NotAvailablePanel (external runtime), api.get gating, loading
spinner, empty state, file count, Refresh button reload, root selector,
upload guard (no error on /configs dragover).

+"""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.

- *   - Template button disabled while deploying

-// @vitest-environment jsdom
-/**
- * Tests for ExternalConnectModal — the modal surfaced after creating a
- * runtime="external" workspace. Surfaces workspace_auth_token + ready-to-paste
- * snippets so the operator can configure their off-host agent.
- *
- * Coverage:
- *   - Renders nothing when info=null
- *   - Opens dialog when info is provided
- *   - Default tab: "Universal MCP" when universal_mcp_snippet present, else "Python SDK"
- *   - Tab switching between all available tabs
- *   - Snippets show with auth_token replacing placeholders
- *   - Copy button: calls clipboard API, shows "Copied!", clears after 1.5s
- *   - Copy failure: shows fallback textarea
- *   - "I've saved it — close" calls onClose
- *   - Security warning: one-time token display
- *   - Fields tab shows raw values
- *   - Tabs hidden when their snippet is absent
- *
- * Fake timers: applied per-describe to avoid mixing with waitFor. Tests that
- * use waitFor (which needs real timers) run without fake timers. Tests that
- * verify setTimeout behavior use vi.useFakeTimers() + act(vi.advanceTimersByTime).

- * Tests for DropTargetBadge — floating drag affordance rendered over the

  *
- * Covers:
+ * Two-layer visual contract:
+ *   1. Ghost preview — dashed rect at the next default child slot
+ *   2. Text badge — "Drop into: <name>" floating above the target
+ *
+ * Render-condition coverage:
  *   - Renders nothing when dragOverNodeId is null
- *   - Renders nothing when target node not found in store
- *   - Renders nothing when getInternalNode returns null
- *   - Renders ghost slot + badge when valid target is found
- *   - Ghost hidden when slot falls outside parent bounds
- *   - Badge text includes the target workspace name
- *   - Badge positioned via screen-space coordinates from flowToScreenPosition
+ *   - Renders nothing when dragOverNodeId node has no name (store lookup misses)
+ *   - Renders nothing when getInternalNode returns undefined
+ *   - Renders badge with correct name when all inputs are valid
+ *   - Badge text contains the target node name
+ *
+ * Note: Ghost visibility (slot rect inside parent bounds) involves
+ * flowToScreenPosition coordinate arithmetic that's better covered by
+ * integration tests that render the full canvas. Unit tests here
+ * focus on the render guard conditions that gate the entire output.
+ *
+ * Issue: #2071 (Canvas test gaps follow-up).

+ *   - Empty state when no tokens
+ *   - Token list rendering (single + multiple)
+ *   - Token age display (just now, minutes, hours, days)
+ *   - New key form: label input + Create button
+ *   - Create: POST with optional name payload
+ *   - Create: loading spinner during creation
+ *   - New-token success box with copy button
+ *   - Copy button writes to clipboard + shows "Copied"
+ *   - Copy auto-resets to "Copy" after 2s
+ *   - Dismiss button hides new-token box
+ *   - Revoke button opens ConfirmDialog
+ *   - ConfirmDialog cancel closes without calling API
+ *   - ConfirmDialog confirm calls DELETE and re-fetches
+ *   - Error banner on fetch failure
+ *   - Error banner on create failure
+ *   - Error banner on revoke failure

- *   - PendingAttachmentPill renders exactly one button
