* feat: zero onboarding, extension version check, and update notifier
- Fail-fast guard in execution.ts: when daemon is running but extension
is not connected, immediately surface a setup guide instead of waiting
for the 30s connect timeout
- Extension version handshake: extension sends `hello` with its version
on WebSocket connect; daemon stores it and exposes via /status; CLI
warns on mismatch in both execution path and `opencli doctor`
- `opencli doctor` now shows extension version inline and reports
version mismatch as an actionable issue
- Non-blocking npm update checker: registers a process exit hook so the
update notice appears after command output (same pattern as npm/gh/yarn);
background fetch writes to ~/.opencli/update-check.json for next run
- postinstall: print Browser Bridge setup instructions after shell
completion install for first-time global install users
Bug fixes caught in review:
- discover.ts: add AbortController timeout to checkDaemonStatus() fetch,
move clearTimeout after res.json() to cover body streaming
- daemon.ts: clear extensionVersion and reject pending requests in
ws.on('error') handler, not just ws.on('close')
- update-check.ts: skip update notice when process exits with non-zero
code; read cache once at module load to avoid double disk I/O;
guard isNewer() against NaN from pre-release version strings
* fix: reduce fail-fast timeout to 300ms and guard stderr.write in exit hook
The postinstall script was appending the fpath line at the end of .zshrc,
but compinit (called earlier by oh-my-zsh or directly) would have already
finished scanning. This caused zsh completion to silently fail for most
users.
Now the script detects the first compinit / oh-my-zsh source line and
inserts the fpath entry before it, ensuring completion works immediately.
