Guard shortcuts during text composition

[DhruvShah-Dev]

Summary

• Add a shared guard for IME/dead-key keyboard events.
• Skip global shortcut handling while text composition is active.
• Skip Monaco shortcut interception during composition so typed characters are left to the editor/input.

Why

Issue #655 reports intermittent focus/selection disruption while typing, possibly around alternate-character input. Composition/dead-key events can look like shortcut keydown events before the final character is committed, so shortcut handlers should not consume them.

Fixes #655.

Validation

• pnpm.cmd exec vitest run tests/hooks/useGlobalShortcuts.test.ts tests/components/ui/SqlEditorWrapper.test.tsx
• pnpm.cmd typecheck
• pnpm.cmd lint
