Claude's TodoWrite checklist was invisible. Add a TaskItem/TaskStatus
model + a latest-wins parser (taskListFrom) that reads the most recent
TodoWrite tool call (it replaces the whole list each time), and a compact
display-only ClaudeTaskDock pinned between the conversation and the
composer: collapsed to "N tasks · M done" + the current in-progress item,
expandable to the full checklist with per-item status glyphs + a11y
labels. Hidden when there are no tasks. Parser + widget tests.
