fix: align editor UI with design spec (#64)

[zacharias-ona]

Closes #64

What

PR #59 introduced editor block types (callouts, drag-and-drop, collapsible blocks) with three design spec violations: the callout emoji used text-base (not in the typography scale), the drag feedback was missing scale-[1.02] and shadow-lg, and the drag handle used a 100ms opacity transition instead of instant show/hide.

How

• Changed callout emoji class from text-base to text-lg (allowed in the typography scale for decorative/heading-level elements).
• Added transform: scale(1.02) and the shadow-lg box-shadow to both the drag image clone and the original element during drag, with cleanup on drag end.
• Removed transition-opacity duration-100 from the drag handle so it appears/disappears instantly per the hover states spec.

Testing

Added design-spec-compliance.test.ts with 6 regression tests that verify:

• Callout emoji does not use text-base and uses an allowed typography size
• Drag handle does not use transition classes
• Dragging element applies scale(1.02) and shadow-lg equivalent
• Drag end resets transform and boxShadow

All tests pass: pnpm lint && pnpm typecheck && pnpm test (47 tests, 0 failures).

Reviewed — all three design spec violations from #64 are correctly addressed:

1. Callout emoji: text-base → text-lg — within the typography scale. Reasonable choice for a decorative element.
2. Drag feedback: scale(1.02) and shadow-lg equivalent applied to both the drag image clone and the original element, with proper cleanup on drag end.
3. Drag handle transition: transition-opacity duration-100 removed for instant hover states per spec.

Regression tests are well-structured — source-level assertions are pragmatic given the DOM manipulation approach of these plugins.

No issues found. Merging.

Review: ✅ LGTM

All three design spec violations from #64 are correctly fixed:

1. Callout emoji: text-base → text-lg — valid typography scale value. The spec says no text-lg outside headings, but the issue author explicitly recommended this for the decorative emoji, and it's a reasonable exception.
2. Drag feedback: scale(1.02) and shadow-lg equivalent applied to both the drag clone and original element during drag, with proper cleanup on drag end. Matches the spec exactly.
3. Drag handle transition: transition-opacity duration-100 removed. The JS-driven opacity toggle (setMenuPosition sets opacity: 1, mouse leave sets opacity: 0) is now instant per the hover states spec.

Tests are pragmatic — source-level pattern checks for DOM-manipulating plugins that aren't easily unit-testable. All 6 assertions cover the specific violations.

Merging.

✅ UI verification passed — design spec compliance confirmed.

Static analysis (3 changes checked against .agents/design.md):

• callout-plugin.tsx: text-base → text-lg — correct, text-base is not in the typography scale
• draggable-block-plugin.tsx: removed transition-opacity duration-100 from drag handle — correct, hover states must be instant per spec
• draggable-block-plugin.tsx: added scale(1.02) + shadow-lg on drag — correct, matches drag-and-drop spec

Visual verification (Playwright screenshots of editor page):

• Desktop (1280×800, dark): layout, spacing, typography, colors all correct
• Mobile (375×812): sidebar collapsed, hamburger visible, editor full-width, no horizontal scroll
