feat(memo): add task list quick actions

[boojack]

Summary

• Add memo task quick actions for checking all tasks and unchecking all tasks.
• Parse GFM task list items with mdast/micromark so code blocks and inline code are ignored.
• Re-render memo markdown content when the content changes, independent of update timestamp changes.

Validation

• cd web && pnpm test markdown-task-actions
• cd web && pnpm test
• cd web && pnpm build
• cd web && pnpm lint

📝 Walkthrough

Walkthrough

This PR adds bulk task-checking actions to memos by implementing Markdown task checkbox manipulation utilities, integrating them into the memo action handlers and UI menu, and fixing a remounting issue in MemoBody by using content-based keys instead of update timestamps.

Changes

Bulk task actions for memos

Layer / File(s)	Summary
Markdown task manipulation utilities web/src/utils/markdown-task-actions.ts, web/tests/markdown-task-actions.test.ts	Implements checkAllTasks and uncheckAllTasks functions using GFM-aware AST parsing and source-range-based checkbox replacement. Edits are applied in reverse order to avoid offset drift. Tests verify behavior across unordered, ordered, and nested lists, plus code-block boundary handling to avoid false matches in fenced or inline code.
Task action handlers and type cleanup web/src/components/MemoActionMenu/hooks.ts, web/src/components/MemoActionMenu/types.ts, web/src/components/MemoActionMenu/index.ts	Adds updateMemoContent callback for persisting memo content with success toast and error handling. Implements handleCheckAllTaskListItemsClick and handleUncheckAllTaskListItemsClick handlers that transform memo content and persist via the callback. Exports handlers from the action object. Removes unused UseMemoActionHandlersReturn type and updates re-exports.
Task actions menu UI and localization web/src/components/MemoActionMenu/MemoActionMenu.tsx, web/src/locales/en.json	Adds task-related icons and a conditional "Task actions" submenu to MemoActionMenu when tasks exist in writable, non-archived memos. Menu items are enabled/disabled based on whether open or completed tasks exist. Adds localization strings for task actions title, check/uncheck labels, and update confirmation.

Content-based remounting

Layer / File(s)	Summary
Content-based key generation web/src/components/MemoView/components/MemoBody.tsx	Adds getContentRevision helper to compute a content-derived string from length and hash. Uses this revision in MemoContent's React key instead of memo.updateTime, causing the component to remount when memo content actually changes rather than on any memo update.
