Empty marker on the last pre-Reload change. Keep the Reload experiment on reload (3801914), its first change on reload-start (200a1fc), and the unfinished performance investigation on reload-perf-wip.

It never did — the effect arm was `.watch => {}` with a comment saying a shell
that never delivers the event simply never reloads. That was written as a
deliberate scope cut and it is the whole bug: the user runs pardes-gui.
The tty watcher was fine, and I proved all four suspicions false against a real
binary in a real pty with the write done by a stranger process and NO input
delivered afterwards: the loop does wake (postEvent signals an empty queue),
zig fmt's rename-over does fire MOVED_TO and is caught, three panes across two
directories all reload and closing one leaves its neighbour still following,
and the self-write hash guard does not swallow a real change. The live session
even had its inotify mark on src with the right mask and re-read config.zig
when I touched that directory.
Duplicated rather than shared with tty.zig, the way the two shells already each
own LspJob, forkShell and their pty readers. The headless PARDES_TEST_GRID path
deliberately passes -1: its contract is one frame per scripted input, and a
reload on its own clock would put an unasked-for frame in the stream.
filewatch.snap proved less than it looked. Its real blind spots were the
rename-over shape — the old script only truncated, so it saw CLOSE_WRITE and
never MOVED_TO — multiple directories, and the one that mattered: the suite
only ever runs the TTY binary, so it structurally cannot see a gui-only
regression. It now uses a new `run` directive whose writer is a child of the
RUNNER, so nothing it does reaches an app pty.

An external update is pushed onto the undo stack exactly like an edit the user
typed, so unsaved work is one `u` away and pardes never has to merge anything.
That is the design, not an implementation detail: the whole feature is
pushUndo() then setContent().
One inotify instance in the tty shell, blocking in readVec through std.Io on a
concurrent task started beside the pty readers — after loop.start(), so the
forkpty ordering is untouched. It watches the containing DIRECTORY, because an
editor rewrites by rename-over and a watch on the file would follow the dead
inode, and it listens for CLOSE_WRITE rather than MODIFY, which is one event per
finished writer and most of the debounce for free.
Our own Save does not reach the undo stack: each watch keeps a hash of the
bytes last seen on disk and save_file restamps it. A hash rather than mtime and
size because the reload has to read the file anyway.
The core stays sans-IO — one watch effect out, one file_changed event in, and a
shell that cannot watch simply never sends the event, which is what the gui and
the web platform do. Linux only; fanotify is what the build system uses and is
rejected in a comment: it exists for thousands of directories across mounts,
and sixteen panes of inotify is a third of the code with no kernel floor.
New golden filewatch: edit without saving, overwrite from a shell in another
column, watch it reload, undo, get the unsaved edit back. None moved.
