arcattackandClaude Opus 5 bf40c53e1e Launchers: make the handoff wait tool-independent -- my first version broke on any PATH carrying Git-Bash/MSYS
Regression in my own fix from an hour ago, reported immediately by the
operator on relaunch:

    find: '/I': No such file or directory
    find: 'btl4.exe': No such file or directory
    The game has exited. ...

The wait loop called bare `find`, which resolves to the MSYS/Git-Bash **Unix**
find on any box with git on PATH (confirmed here: `which find` ->
/usr/bin/find, `which timeout` -> /usr/bin/timeout).  So the loop errored out
and fell straight through -- restoring exactly the misleading "The game has
exited" message it was meant to remove.  `timeout` was the same exposure one
line later (GNU coreutils ships one, with different arguments), so the block
had TWO PATH-dependent failures.

Harmless to the game (the loop only reports; it never touched the session),
but it made the fix a no-op for anyone with git installed -- which is every
developer and a fair number of players.

FIX: no external tools at all.
  * detection is now a pure-cmd `for /f "tokens=1"` over tasklist output,
    comparing the first token to btl4.exe -- no find/findstr;
  * tasklist and timeout are both invoked by ABSOLUTE %SystemRoot%\System32
    path, so a shadowing PATH cannot reach them.

Failure modes stay safe: if tasklist is unavailable the variable never gets
set and the loop degrades to reporting immediately (the old behaviour, never a
hang), and a genuinely dead exe still falls straight through so the #41 launch
forensics are untouched.

VERIFIED both branches by running the shipped detection lines from THIS bash
shell -- i.e. the hostile shadowed PATH that broke v1, a harder case than a
playtester's clean environment:
    game running        -> RESULT: WOULD-WAIT [process detected]
    absent-name control -> RESULT: WOULD-EXIT [no process]
No find/timeout errors in either.

(players/ is the shipped source per tools/mkdist.py:78; the gitignored root
copies re-synced byte-identical.)

rem HANDOFF WAIT (2026-07-25). The front end does NOT stay resident: it
rem CreateProcess()es the mission generation and ExitProcess(0)s itself
rem (btl4console.cpp). So OUR child exiting means "the menu handed off",
rem NOT "the game closed" -- without this wait the window announced "The
rem game has exited" while the game was still loading, which reads as a
rem crash to a playtester. Wait for the handed-off generation(s) to go.
rem
rem NO EXTERNAL TOOLS: `find`, `findstr` and `timeout` are all shadowed by
rem Git-Bash / MSYS / GnuWin32 builds of the same names when those are on
rem PATH (a dev box, or a player who installed git). The MSYS `find` is
rem the Unix one and dies with "find: '/I': No such file or directory",
rem and GNU `timeout` takes different arguments. So: parse tasklist with
rem a pure-cmd for/f, and call both helpers by ABSOLUTE System32 path.
rem A genuinely dead exe leaves no process and falls straight through, so
rem the #41 launch forensics above still work. If tasklist is missing
rem entirely the loop degrades to reporting immediately -- the old
rem behaviour, never a hang.
