DEDUP: a re-upload of identical content at a DIFFERENT rect was deduped by
hash+size, keeping the stale rect -- origins computed from it were off by the
position drift. Dedup now requires the same position; the origin/src handed to
the renderer come from the live containing upload. NOTE: this did NOT cure the
strip vertical offset (top row cut, bottom duplicated) -- that symptom persists
on screen and its root cause is still unidentified. The change stands on its
own correctness, not as that fix.
SAVESTATE SECTION (BS_SEC_TEXPACK): written and applied correctly in isolation
(telemetry showed 1360 entries rebuilt from the state's own VRAM), but with the
section present the overall state load FAILS in a LATER section, cause not yet
isolated -- and old builds hard-reject unknown tags (`default: return 0`), so
the section also breaks backward compatibility. The boot_state wiring is
REVERTED; tex_pack_state_bytes/write/apply remain, dormant, for whoever picks
this up with the loader diagnosis. Until then: after loading a savestate,
textures the game does not re-upload stay low-res -- known limitation again.
The first-save defer fix verified working in passing: "deferring slot 4 -- no
safe resume PC (hint=0x00000000)" followed by a save at a real PC.
