Track an open GP0(A0) upload in the renderer whatever the HD state
(facade gr_vram_upload_begin/commit/set_open): HD activation mid-A0
waits for the commit instead of reading the FBO over received words,
and a full-VRAM load no longer ends the hold; gpu.c restores it from
gp0_state on load and ends it on GP1(01h). Sync the render thread
before flushing dumps or reading HD diagnostics, suppress dumps from
generated frames, use _putenv on MinGW, drop a stale log. Adversarial
fixtures for both cases in full-VRAM and high-resolution-window modes.

HD texture packs matched draws on the render thread but tracked uploads and
invalidations on the emulation thread, hashing gpu.c's array: a data race
(crash seen in hd_texture_pack_match) and wrong identities whenever the
emulation thread had already recorded a later upload.
The facade now sends residency changes through an optional backend hook
(hd_texture_note). The render-thread backend records them as RTH_HD_NOTE
after the upload/draw they follow; the replay hashes the render thread's own
VRAM copy, which the HD module now follows with the SW rasterizer
(gpu_hd_textures_bind_vram). Pack (re)configuration and HD mode changes are
sync points. Other backends apply the change immediately as before.
The HD GL fixture gains a render-thread case (fails without this change)
and links again: the scale fixture's facade stubs no longer collide with
the real gpu_render.c it includes.

Rewind and in-session savestate loads have no sidecar. Each Beetle-keyed
upload rectangle seen in the session is remembered (at most 256); after a
restage it becomes resident again only if the restored words still hash to
a replacement key, so the HUD keeps its replacement across loads.

A savestate restage cleared every upload identity, so a texture uploaded
once (a race HUD) lost its replacement after any load until the game
uploaded it again. Saving a slot now also writes the Beetle-format residency
beside it (*.hdres: host metadata, never in the .pst), bound to a CRC of
the whole native VRAM. A load restores it only over exactly that VRAM, so
no identity is fabricated; anything else falls back as before.

Load modern texpage/texupload PNG replacements independently of DuckStation source. Integrate pack folders and options with mods, preserve native VRAM, and validate GL rendering, format matching, dump safety, and upload invalidation.
