Baixar TermCanvas 0.38.2 per a Windows

Added
- Markdown sanitization: rendered markdown (session replay, agent bubbles, etc.) now passes through DOMPurify before insertion via dangerouslySetInnerHTML. Defense-in-depth against any future provider that ships HTML in message text.
- Copy buttons in session replay: every user prompt and assistant text row gets a muted copy icon at the bottom-right (brightens on hover, swaps to ✓ for 1.2s on success). Source is TimelineEvent.textPreview, capped at 16 KB by the scanner — covers the 95th-percentile message.
- Zustand setState-loop debug middleware (wrapSetState): traces high-frequency setState calls during dev so future "max update depth" regressions surface as a counter instead of a crash.
Changed
- Session replay footer: removed the progress bar. The highlighted-row indicator already shows position, and the bar crowded the footer. Play/pause/seek controls stay for keyboard stepping.
Fixed
- Title input dragged the whole tile: clicking-and-dragging inside the custom-title input was moving the node instead of selecting text — onMouseDown stopPropagation doesn't help because React Flow detects drag from pointerdown. The title container now carries the nodrag opt-out; rest of the header stays draggable.
- Pin drawer never reopened after a transient list failure: pinStore.openDrawer cached an empty array on rejection, short-circuiting every subsequent open for that project. The cache key now stays unset on failure so the next open retries.
- One corrupt pin file aborted the whole list: PinStore.list() threw on the first malformed .md, hiding every other pin in the repo. Per-file errors are now caught, logged, and skipped. readFile also validates required string fields and ID_REGEX before constructing a Pin.
- Invalid pin status silently accepted on create: PinStore.create skipped the status validation that update already had, so a CLI-created pin with a bad status would write to disk and then vanish from list/get. create now throws PinStoreError 400, matching update's contract.
- Pin dispatch errors said "Task": legacy "Task not found" copy and [Task] log prefixes leaked through pin.dispatch.failed toasts after the rename. Renamed to "Pin" everywhere; stale TERMCANVAS_DIR/tasks/ comments updated to pins/.
- pnpm test skipped the entire Pin feature: the script still listed deleted task-*.test.ts files instead of the renamed pin-* equivalents. Replaced.
- wrapSetState broke the release-build typecheck: the wrapper's forwarded (partial, replace) didn't match either zustand setState overload. Single function-cast at the forwarded call; runtime semantics preserved.

- CLAUDE.md: documented the TermCanvas Pin system — when to record a pin, the termcanvas pin CLI surface, and conventions for capturing user-deferred work.
