fix(status): watch for create, so a mode's first write is seenHEADmaster

Qt's atomic write builds the file as an unnamed O_TMPFILE. When the
target does not exist yet it links that straight into place, and the
only event naming the file is IN_CREATE: no close_write, no moved_to.
statusctl watch did not listen for create, so the first write of each
mode in a session went unseen. On a fresh session that is the write
that matters: a Teams call started an hour in left the waybar pill
reading off until some later rename happened to redraw it.

The test reproduces the event with a hard link, which is what the
linkat from Qt's temp file looks like to inotify.
