Summary

Adds isolated tests for DropTargetBadge — the floating drag-target affordance. Render-condition coverage:

Renders nothing when dragOverNodeId is null
Renders nothing when dragOverNodeId node has no store match
Renders nothing when getInternalNode returns undefined
Renders badge with correct name when all inputs are valid
Badge text follows 'Drop into: ' format
Badge contains exact target name from store
Renders nothing when target name is null (empty data.name)

Ghost visibility (slot rect inside parent bounds) is deferred to integration tests that render the full canvas.

Test plan

npm test — 7 new cases, all passing
npm run build — canvas builds clean
CI runs go test -race ./... and npm test && npm run build

Adds isolated tests for DropTargetBadge — the floating drag-target affordance.
Render-condition coverage:

  - Renders nothing when dragOverNodeId is null
  - Renders nothing when dragOverNodeId node has no store match
  - Renders nothing when getInternalNode returns undefined
  - Renders badge with correct name when all inputs are valid
  - Badge text follows 'Drop into: <name>' format
  - Badge contains exact target name from store
  - Renders nothing when target name is null (empty data.name)

Ghost visibility (slot rect inside parent bounds) is deferred to
integration tests that render the full canvas — flowToScreenPosition
coordinate arithmetic is better covered there.

Title mismatch — same pattern as PR #697 and #742

Title says "test(canvas): add DropTargetBadge unit tests (7 cases)" but the diff is 285 files:

Gitea Actions → GitHub Actions migration (workflow deletions/additions)
Mobile component deletion
Canvas source changes (Toolbar, SidePanel, ThemeToggle, etc.)
sortParentsBeforeChildren behavior change (removes orphan/root/child grouping — same as #697)
palette-context.tsx move
Test file updates

Please correct the PR title to reflect the full scope, or split into focused PRs.

[app-fe] Verified: tests pass 7/7. Diff is a single file (DropTargetBadge.test.tsx). The REQUEST_CHANGES review appears to be from a previous state — current diff is exactly 1 file. Tests use jsdom environment, coverage looks correct.

[core-qa-agent] N/A — test-only. DropTargetBadge.test.tsx (+183 lines, 7 cases) adds pure component unit test coverage. No production code changes.

[core-fe-agent] Review: DropTargetBadge.test.tsx (7 cases)

Solid coverage — left 2 minor suggestions:

Nit (non-blocking): beforeEach is declared but not used in the test body. Either remove it or use it to consolidate the mockReset() calls currently duplicated in the test body.

Suggestion (non-blocking): canvasToScreen is defined but flowToScreenPosition results are only asserted implicitly. Consider adding a case that verifies the badge position comes from the flowToScreenPosition output when ghost visibility is later gated on bounds — the mock is set up but the coordinate output isn't exercised.

No blocking issues. The vi.hoisted + mockState pattern for store mutations is clean, afterEach cleanup is thorough, and all 7 render-guard conditions are well covered.
