Matthew Stanley 5b7e69b441 Remove the sljit Tier-2 in-process JIT backend
The tier mis-compiled and has been hard-gated off since 2026-06-25; overlay
gaps fall to gcc/tcc shards and the dirty-RAM interpreter, unchanged.

Re-do on master of the removal validated on the stale branch (6da8c02),
reconciled with everything master grew since the fork:

- Delete overlay_sljit.{c,h}, overlay_compile_worker.{c,h}, lib/sljit,
  runtime/tests/sljit_*.c, and the runtime.cmake sources/include-dirs.
- Strip the sljit provider/backend from code_provider.{c,h},
  overlay_backend.{c,h} ("sljit" in overlay_backend/PSX_OVERLAY_BACKEND now
  degrades to auto so stale configs still boot), main.cpp, debug_server.c
  (sljit_status/sljit_async/sljit_try TCP commands), overlay_loader.{c,h}
  (live policy, JIT-on-miss, persisted-shard cache, async worker glue,
  psx_sljit_call/cop2/memx host helpers — reachable only via the removed
  cpu->sljit_helpers table), and cpu_state.h (SLJIT_HLP_* enum + the
  sljit_helpers[] member; CPUState layout change reshards via the cg tag).
- Master-only entanglement resolved before deletion: 28165d6's Einhander WS
  player-X bound emit existed in three paths (gcc code_generator, sljit,
  dirty_ram_interp). The gcc shard link contract now forwards
  psx_ws_player_x_bound (ABI v13, previous commit), so deleting the sljit
  emit path loses no widescreen behavior; ffc6688's game-dispatch block
  inside the dead psx_sljit_call helper goes with it.
- Reword comments that described sljit as a live backend (gpu.{c,h},
  ws_*_detect.h, cosim_state.c, dirty_ram_interp.c, autocompile.h,
  boot_state.h, config_loader.h, compile_overlays.py, and the CPS marker
  comments the recompiler emits).

recompiler psxrecomp-game builds clean; game runtimes rebuilt + boot-verified
separately.

Matthew Stanley ee09ab9bbb widescreen: generic Ape-Escape-class support + native-wide GL perf + cutscene flicker fix
Adds full 16:9/21:9 native-wide support for fully-3D titles (Ape Escape,
SCUS-94423) as a generic, opt-in, 4:3-byte-identical framework capability, plus
a native-wide GL compositor perf fix and a cutscene present-mode flicker fix.

Widescreen (generic, per-game opt-in via [widescreen*]):
- Shared screen-extent cull detector (runtime/include/ws_cull_detect.h) used by
  all three backends (recompiler, dirty-RAM interp, sljit). Per-game signature
  immediates ([widescreen.cull] screen_w_imms/screen_h_imms) — Ape's funnel
  tests 0x181/0xF1 on its 368px display, not Tomba's 0x140/0xE0.
- Three funnel idioms widened: unsigned per-vertex sltiu (psx_ws_cull_sltiu),
  signed min/max slti right edge + bare-bltz left edge (psx_ws_cull_slti/bltz,
  new helpers + SLJIT_HLP appends), and billboard center+/-halfwidth. Explicit
  [widescreen.cull] slti_sites for X-only funnels the auto-detector can't
  qualify.
- gte_game_mode: GTE-activity gameplay detector for 3D titles with no sprite-tag
  helper (gte.cpp notes every RTPS/RTPT). STICKY (>=3 verts, 45-frame hysteresis)
  so sparse cutscene frames never flip to a 4:3 pillarbox = fixes intro flicker.
- nw_hud_corners: push outer-third screen-space HUD sprites to the true wide
  corners in native-wide (else inset by the reveal).
- nw_backdrop: stretch a full-frame axis-aligned 2D backdrop quad to fill the
  wide frame (for titles with a flat sky plane).
- Pattern-scanned interp/sljit widen hooks now gated per-game (auto_screen_x /
  auto_backdrop): fixes an ungated auto_backdrop false-positive that rewrote a
  live GPR = the ~24s native-wide crash on Ape.

Native-wide GL perf (fixes 16:9 frame drops):
- The wide surface centre equals the canonical 4:3 framebuffer, so wide_blit_center
  copies canonical->wide-centre at present (both present paths) and the per-prim
  mirror SKIPS prims fully inside the 4:3 frame (mirror_x/geo/batch_center_only).
  Only reveal-margin prims re-rasterize. Peak frame time 38.8ms -> 17.5ms, no
  vsync misses. Toggle gl_wide_fast; 4:3 untouched (all gated on g_wide_cur).

Runtime-only except the recompiler cull emit (regen needed for cull widening).
