On Linux/Windows @parcel/watcher uses a brute-force backend that recursively walks the entire tree on a libuv threadpool thread before subscribe() resolves. Opening a large folder backed by slow storage (a home directory on NFS) as a worktree and watching it (file explorer) can make that crawl run for minutes, holding a threadpool slot and starving every other async fs/crypto op. On the headless serve runtime this wedges all clients — even a static HTTP asset (which needs fs.stat + createReadStream on the same pool) returns 0 bytes and times out. This matches the os:linux + NFS + non-git-home-dir trigger in #5308. - Race the initial subscribe() against a 15s timeout; on timeout the watch fails cleanly (explorer still works via manual reads, just no live updates) and the slow subscription is dropped if it ever resolves. - Bound the per-batch stat() fanout to 8 concurrent calls so an event burst can't occupy every threadpool thread at once. This complements the git-runner default timeout: together they close the two ways the non-git-folder-as-worktree trigger could starve serve. Co-authored-by: Orca <help@stably.ai>

Features
Also in the box:
- Quick open — Search across worktrees, files, agents, commands, and repo context without leaving your flow.
- Account switcher & usage tracking — See Claude and Codex usage and rate-limit resets, and hot-swap accounts without re-logging in.
- Rich repo previews — Preview Markdown, images, PDFs, and repo docs in the workspace.
- Computer Use — Let agents operate desktop apps and visible UI when a workflow needs real interaction.
- Notifications and unread state — Know when an agent finishes or needs attention, then mark threads unread to come back later.
- And many, many more — we ship daily, so this list is perpetually behind. The changelog is the real feature list.
