Fix Tapwrite content update loop on task detail

[cursor]

Changes

• Added a deferred Tapwrite content callback hook to avoid synchronous React state updates during Tapwrite/Tiptap transactions.
• Applied the guard to task detail Tapwrite consumers: task description, subtask description, comments, and replies.

Testing Criteria

• Ran yarn eslint "src/hooks/useDeferredTapwriteContent.ts" "src/app/detail/ui/NewTaskCard.tsx" "src/app/detail/ui/TaskEditor.tsx" "src/components/cards/CommentCard.tsx" "src/components/cards/ReplyCard.tsx" "src/components/inputs/CommentInput.tsx" "src/components/inputs/ReplyInput.tsx" (passes with existing repo warnings).
• Ran yarn tsc --noEmit --pretty false (blocked by existing SVG module resolution errors in src/icons/index.ts, before any changed-file errors).

Notes

• Linear/Sentry: OUT-3775 / TASKS-8D.
• Sentry Seer autofix analysis was unavailable due to budget (HTTP 402), so root-cause analysis was based on Sentry event details and code inspection.

Impact & Surface Area of Change

• Affects Tapwrite-backed editors on the task detail route: task description, subtask creation description, comment input/edit, reply input/edit.
• Regression focus: editing/saving task descriptions, submitting comments/replies, editing existing comments/replies, attachment upload callbacks in these editors.
