feat(chat): prompt navigator list preview, prompt filtering, shell status fix (#2211)

* feat(chat): prompt navigator list preview with prompt filtering The hover preview is now an interactive scrolling mini-list of prompts: rows render as bordered two-line cards, the highlighted row stays inside a center dead zone and the list glides only near the window edges, wheel steps the highlight, and the panel stays open when the pointer moves into it so a click can be corrected inside the list. Rail entries are filtered to real prompts: previews are built from normalized user display parts (synthetic context stripped), fully synthetic user messages are excluded, and shell-mode messages show their extracted command via the shared shell bridge helpers. * fix(chat): render shell command status transitions The injected /shell text part carries live state in shellAction, which the render-relevant part comparator ignored — a running→completed update reached the store but never re-rendered the message row until the next send. Compare shellAction command/output/status for text parts. * fix(sync): stream shell bridge part updates while running Streaming suspension keeps part updates out of the static message records while an assistant message streams, relying on the live streaming-tail path to render it. Shell-mode bridge messages are hidden from the timeline and rendered inside the user row, so they have no live path — suspension froze their output chunks and left the card without a Show output action until the run finished. Exempt shell bridges (single bash tool part parented to a synthetic shell-marker user message) from suspension; their updates arrive at command-output pace, not delta pace. * feat(chat): syntax-highlight shell command card Render the shell-mode command and its output through the shared WorkerHighlightedCode (Shiki) with bash grammar, matching the bash tool part presentation, instead of plain pre blocks.
