Krzysztof kuhy Rudnicki 39e52d07c2 Stop the recovery tick stealing our own grab, and fix pre-commit for the monorepo
`_holds_grab` asked `grab_current() is self._root`, but our own transient
children take the grab for themselves: a posted Tk menu grabs the menu
window, so the test read "the grab was lost" and `grab_set_global()` took it
back a second later, off our own widget mid-interaction. That is what made
screen-locker's sport selector unusable while locked on 2026-07-26. The
predicate is now `grab_current() is not None` -- any window we own means the
lock still has pointer and keyboard -- and it is public, `holds_grab`, so an
embedder can ask the same question instead of re-deriving it. Anything that
does not resolve against our widget map (a Tcl-created `ttk.Combobox`
popdown, a stale name) raises `KeyError` and counts as lost: fail closed,
because losing a popdown beats believing we hold a grab we do not. The
blind spot for a second `tk.Tk()` reporting its root as "." is unchanged from
the old test, and now written down.

`_verify` and `_drain` scheduled the next tick *after* running it, so any
exception ended all re-assertion of coverage, grab and VT for the rest of the
lock -- the exact fail-open this module exists to prevent, in a file whose
docstring is a monotonicity proof. The reschedule moves into `finally`, and
the warnings only fire when the reason changes: these states can last the
whole lock, and a 1Hz journal stream is not the alternative to silence.

The pre-commit side: both subproject configs were written as if cwd were the
subproject, but pre-commit runs hooks from the git root -- which is ~/utils,
not gatelock. Every pushed run since at least 2026-07-11 has been red, and
for compounding reasons: pylint and bandit could not find their config,
bandit's tests exclusion never matched, the pytest hook ran with no config at
all, and with no `files:` filter each config linted the *whole* monorepo, so
gatelock's mypy was type-checking crdt-sync. All paths are now root-relative,
each config is scoped to its own subproject, and the pytest hook goes through
a shared `scripts/run_subproject_tests.sh` that supplies the missing `cd` and
fails loudly if the subproject is gone.

Scoping via `files:` has one sharp edge -- rename the directory and the regex
matches nothing, so every hook passes on zero files, green and useless. An
`always_run` scope-guard hook turns that silent pass into a failure.

bandit 1.7.10 threw inside its AST visitor on Python 3.14 and *skipped* every
file while still reporting zero issues; 1.9.4 actually scans. Codespell was
also flagging a real typo the noise had buried.

Housekeeping the above turned up: `gatelock/.github/` and `crdt-sync/.github/`
were dead -- GitHub only reads the root `.github/workflows`, which already has
all four jobs -- and the two subproject `.gitignore`s were byte-identical to
each other and subsumed by the new root one.
