fix(flowext): a locked screen wedges the rig; and open location opened the wrong browser

Browse Source 
1. LOCKED SCREEN. With CGSSessionScreenIsLocked=Yes, every AppleScript window/tab query
   hangs ~2 min and returns -1712 "AppleEvent timed out". This is NOT a browser bug —
   with m3ultra locked, `count of windows` hung identically for Chrome, Brave, Finder
   AND System Events, while app-level properties (name/version/running) answered instantly.
   launch.sh now checks the lock first and exits 0 with an instruction, so the 10-min tick
   retries instead of leaving two osascript processes wedged.

2. `open location "$URL"` is Standard Additions: it hands the URL to the DEFAULT browser,
   never to $BROWSER. m3ultra's default is Brave while the extension lives in Chrome, so
   the fresh-open path would have opened the wrong browser entirely. Now makes the tab
   inside the target app.

3. Wrapped the tell block in `with timeout of 30 seconds` so a wedged app can't hold the job.

Verified: detector reports unlocked on ultra / LOCKED on m3ultra; after the fix m3ultra
logs the instruction and exits with no hung osascript, ultra still logs "focused on Flow".
