tiles: default the store to user://tile_cache/<seed>, not ~/.cache

~/.cache WAS THE BUG. rsync-excludes.txt excludes ".cache/" -- a pattern with no
internal slash, so it matches a directory of that name at ANY depth. So the
generator was writing its only copy of every tile into the one tree the backup
deliberately skips. Each tile is ~131 s of inference (measured 2026-09-03) and
there are 971 of them.

Verified both directions with the REAL exclude list, against a synthetic tree
rooted the way the real job roots (/home/fleeky, --relative): the new path WOULD
copy, the old one is excluded. My first check was invalid because I made
~/.cache the transfer root, which puts the pattern above the root where it can
never match -- worth noting, because that mistake reads as a passing test.

Tiles are GAME STATE, not a cache, so they belong under Godot's user:// for
hyper-tps alongside everything else the game generates. Verified transparent:
--list still reports 841 / 724 / 564 / 314 / 50 at the new path.

THE SEED IS THE ONLY PARTITION AXIS, and the header now says why. A room is WHO
MAY SEE a tile, not what it is: two rooms on one seed have byte-identical
terrain, so nesting by room duplicates it -- the same reason hyper-tps keys
user://content by hash, "two rooms asking for the same asset share one copy". A
map SELECTS a seed and generator config; it is not an identity axis. Room and
map scoping belong to KeetTileIndex and StateBase, not to directory names.

bench_cpu_tile.py DID NOT READ LOOKDEV_TILE_CACHE at all -- it had the path
hardcoded, so it silently benchmarked a different tile set than stitch_block.py
and server.py were looking at. Now it reads the env var like the other two.
