History
Krzysztof kuhy Rudnicki a8b34befb5 Lend the lock screen's grab to the workout app, without unlocking it 
The locker cannot close() to let the app take over: close() also restores VT
switching, which would hand the user Ctrl+Alt+F2 and an exit from the very
obligation the lock exists to enforce. Only the grab moves; the Tk window
stays mapped underneath, so the screen is still covered if the app dies.

The watchdog has to be stopped for the duration, and measuring it is what
makes that non-negotiable. gatelock's recovery loop re-takes any grab it
finds missing every 1000ms -- by design, so that pulling a cable is not an
escape -- and holds_grab() is `grab_current() is not None`, which is False
once another X client holds it. Verified on a private Xvfb display: a naked
release is stolen back within ~1.5s, while stopping the loop first lets the
app keep the screen and the locker take it back cleanly afterwards.

The same harness confirms the ordering the handshake depends on: while the
locker holds the global grab a second X client cannot even finish connecting
(4s, no output at all), so there is no window in which the screen is
uncovered. It only gets through after the release.

Reaching into lock._recovery earns an SLF001 waiver rather than a public
pause on LockWindow: gatelock's _recovery.py carries a monotonicity proof
that no transition ever decreases the grab, and a public lend_grab() would
be exactly that transition. The waiver is documented where the other four
SLF001 waivers in this repo already live.

start_workout blocks the Tk loop for the whole workout, which is deliberate
-- pumping Tk underneath is what would let a tick steal the screen mid-set.
The docstring names the cost: a monitor hotplug is not handled until the app
exits and grab_input() re-covers every live output.
