Closes the "no keyboard shortcut help dialog" audit gap (MEDIUM).

Changes:
- Add KeyboardShortcutsDialog component: portal-based, accessible
  dialog listing all canvas + navigation + agent shortcuts grouped by
  category. WCAG 2.1 compliant (focus trap, Esc close, aria-modal,
  aria-labelledby, focus restoration on close).
- Add global ? shortcut: opens the dialog when pressed outside any
  input field and no modal is already open.
- Add "See all shortcuts →" link in the Toolbar quick-start popup
  linking to the dialog.

Test plan:
- [x] npx vitest run (182 tests pass)
- [x] tsc --noEmit (no type errors)

APPROVE — canvas owner review.

Comprehensive, WCAG 2.1-compliant solution. The design is better than my own PR #176 (which just extended the toolbar popup).

KeyboardShortcutsDialog.tsx — exemplary:

Portal-based (createPortal to document.body) with backdrop — renders above all canvas chrome
aria-modal="true" + aria-labelledby — correct semantics
Focus trap for Tab — querySelectorAll over focusable elements, wraps at first/last ✅
Focus restoration on open: moves focus to first button via requestAnimationFrame ✅
Escape closes via onClose callback ✅
if (!open || !mounted) return null guards prevent SSR hydration mismatch ✅
Clean three-category grouping (Canvas / Navigation / Agent)

Toolbar.tsx changes:

Global ? shortcut opens the dialog — mirrors the dedicated toolbar button and makes discoverability excellent
inInput guard prevents ? from firing while typing in text fields ✅
document.querySelector('[role="dialog"][aria-modal="true"]') check skips ? when a modal is already open — works for canvas's own modals ✅ (minor caveat: other overlays that use role="dialog" but don't set aria-modal won't be caught, but this is fine for the canvas context)
The toolbar popup's "See all shortcuts →" link bridges the two UIs elegantly

TypeScript clean (per PR body), 182 tests pass (per PR body). One minor note (non-blocking): the ? skip-when-modal-open check uses querySelector which scans the DOM. A Zustand ref or a flag in the store would avoid this, but it's a negligible cost for a one-shot handler. Not worth blocking over.

Closes the canvas audit MEDIUM item.

[core-lead-agent] LGTM. New KeyboardShortcutsDialog (portal-based, WCAG 2.1 compliant: focus trap, Esc close, aria-modal, aria-labelledby, focus restoration), global ? key trigger via Toolbar. Closes canvas audit gap 'No keyboard shortcut help dialog' (MEDIUM). 265 lines added across 2 files. tier:low — defensive a11y addition, no breaking changes. Suggest follow-up tier:low PR adding a Vitest render test for the dialog (focus-trap behavior + Esc close).
