* feat(widescreen): continue framebuffer-feedback sprites into native-wide bands
Titles tag a 15-bit sprite that copies a framebuffer 1:1 (gpu_ws_tag_feedback_rect / psx_mod_tag_feedback_rect). Where it touches the draw area's edge, gpu.c emits band spans and the new optional backend op wide_feedback_rect (GL incl. render thread, software) samples the source buffer's wide surface. Band texels count as bit 15 set, as the centre does once the trail blends.
The software rasterizer now writes the texel's bit 15 into the framebuffer, and wide_full can dump the surface alpha ("alpha":1).
* fix(widescreen): quantise band feedback like packed VRAM
The centre samples 5-bit packed VRAM each frame; the band copy read the 8-bit wide surface and modulated with /128, so the bands drifted ~3 grey levels brighter and left a step at the 4:3 edge. Truncate like PACK_FS and modulate like TEX_FS.
* Reject fully clipped sprites before extending feedback margins
* Complete isolated resident and PGXP fixture collaborators
* Preserve existing line endings in the review fixes

Review 2 (mstan): psx_mod_read_* in a host-output hook now peek RAM /
scratchpad / BIOS ROM (psx_peek_word) and read MMIO as 0, so SIO data / stat
reads no longer pop RX or age the ACK. The CPUState copy's bus pointers are
replaced: reads peek, writes are dropped, so cpu->write_* cannot reach the
shared guest. psx_mod_call_guest_uncharged_counted clears *counted_cycles on
refusal. netplay_view_mods_test now runs the real sio.c behind the bus: the
host-output callback reads SIO_DATA / SIO_STAT through both the mod API and
cpu->read_*, and stores through cpu->write_* (RAM and SIO_CTRL); it checks 0
MMIO bus accesses, SIO stat / ctrl / RX unchanged, RAM unchanged. Other tests
linking mod_runtime.cpp get a psx_peek_word stub.

Preserve negotiated content and dual-raster pass gates. Retain both fixture assertion sets and HD-off seams. Regenerate both BIOS with actual native emitter. Fix type-only rollback corrections and exclude extra-pad changes from digital-only promote gates.
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.
A [[plugin]] may declare netplay = "local_view": it only changes what one
player sees. A netplay session now keeps the player's own features whose every
contribution is such a plugin (no writes, overlays or derived discs) instead of
clearing them, without saving state.toml. They activate as usual, but their
hooks run only inside psx_mod_render_local_view (psx_mod_local_view_scope) and
their vblank/savestate callbacks not at all. With such a plan the widescreen
cull margin is the stock 0 in the shared game and this peer's own margin only
inside the sandboxed own-view draw; squash is not used. The canonical frame,
snapshots and digests stay identical on every peer whatever each player chose,
so nothing is negotiated, and each keeps their own aspect.
Tests: netplay_view_mods_test (flag, plan filter, parked hooks, no vblank,
state.toml untouched), ws_local_view_margin_test (margin scope), render-pass
sandbox asserts the scope around a local view.
