Add three static PAK-format decoders in the Bevy-free formats crate and
present them in the explorer:
- t8ad.rs: linear 32bpp A8R8G8B8 2D texture (UI/HUD art). Dims at
0x14/0x18, header size keyed by the type field @0x1c (container-safe).
Decodes the ~85% RGBA variants; defers the rest (likely DXT) rather
than misdecoding.
- ratc.rs: nested resource bundle — lists named children by magic scan.
- lsta.rs: sprite list — walks the inline T8aD frames.
Viewer: PakContent gains T8ad/Lsta/Ratc, decoded off-thread and bounded
by an 8M-texel per-entry cap; detail views show the texture, a sprite
grid, and a child list with thumbnails. Decoded images carry a
"colours unverified" note — channel-order/sRGB stays on the dynamic-RE
backlog.
Tests: 12 new unit + 3 real-disc (T8aD >=70% decode over the hangar
pack, LSTA frames, RATC named children incl. a decodable T8aD).
