chore(exclude): promote the wave exclude list to config/wave_exclude.txt

There were NINE session-snapshot copies under .run/ and no way to tell which was
current — the accumulation smell behind the whole staleness problem. This is the one,
it is tracked, and it is regenerated rather than hand-edited.

.run/ is gitignored scratch, which is the wrong home for it: CARVE-BLOCKED entries are
derived and vanish when the subseg is split, but WALL entries are CURATED and cannot be
re-derived — that is precisely why the file needs to be tracked.
