texture_disc.rs and mesh_disc.rs fall back to "/home/fabi/RE Project Sylpheed/..."
when SYLPHEED_ISO / SYLPHEED_RES3D are unset. The directory is "RE - Project
Sylpheed"; the fallbacks were missing the " - ", so stage_models_decode,
stage_models_sweep and stage_models_quality_audit failed with NotFound for anyone
who did not happen to know the env var. They now pass unaided (10/10 in
mesh_disc).
Found while auditing what the suite actually exercises after withdrawing the
anchor change: an ISO-gated test skipping, and an ignored test failing on a typo,
are both "green" in a normal run.
Full state, with SYLPHEED_ISO/DISC/RES3D set and --include-ignored: 82 lib tests
and every disc/ISO suite pass; the single failure is
shared_resources_decode_identically_in_every_container, which is deliberately
written as the target state and #[ignore]d.

Reworks the XPR2 texture path after RE against the retail disc (viewer
previews were scrambled/failed).
- de-tile: replace the naive Morton-over-32×32 approximation with the
faithful Xenos Tiled2D bank/pipe/macro-tile address formula (ported
from xenia texture_address.h). Verified correct: the Acheron backdrop
decodes to a sharp planet with its spiral storm.
- endian: undo the X360 word byte-swap per the fetch-constant endianness
field (k8in16/k8in32/k16in32) — without it BCn/ARGB data is noise.
- cubemaps: parse TXCM resources (skybox/backdrops), decoding face 0,
instead of erroring "No TX2D found".
- A8R8G8B8: correct channel order after the k8in32 swap ([A,R,G,B]→RGBA)
— the Acheron backdrop is now correctly green, not red.
- XPR files are texture PACKS; add XPR_RES_INDEX to select a resource.
- CLI `texture export` now writes real PNGs (texpresso BCn decode +
image), replacing the stub. Adds texpresso + image deps.
- tests/texture_disc.rs: integration test running the pipeline over real
disc .xpr files (28/28 parse). RE debug knobs: XPR_NO_DETILE /
XPR_NO_ENDIAN / XPR_FORCE_ENDIAN.
KNOWN ISSUE: mipmapped DXT1 textures still decode to noise — mip 0 is
not at base_address in the multi-resource packs (localized to a mip
storage-offset quirk; uncompressed + de-tile + endian are all verified).
