Left-edge counterpart to slti_sites: emit psx_ws_cull_bltz at configured
bltz PCs. detect_cull_bltz_sites only classifies left-edge bltz for
auto_screen_x-qualified functions, so an X-only funnel wired via explicit
slti_sites had no left-edge widen. bltz_sites closes that gap. Identity at
4:3; regen-class.

Add a conservative source-checkout setup helper based on the Linux quick-start intent from PR #54.
The script builds the CLI/recompiler tools, refreshes BIOS C when a BIOS is present, and builds the BIOS-only runtime only when BIOS/generated sources are available. It deliberately leaves game project creation to the existing CLI generator.

Jackie Chan Stuntmaster (SLUS-00684) hard-blackscreens after the intro
logos: the game's exception dispatcher is re-entrant by design. Its
stage-1 handler saves SR/EPC to a single save slot, then executes
mtc0 CAUSE,0x100 + mtc0 SR,0x101 and relies on the resulting COP0
SOFTWARE interrupt (CAUSE.IP0 & SR.IM0 & IEc) to vector into its
stage-2, which acks the CD INT at the controller, delivers events, and
restores the saved SR. The runtime only ever considered the INTC line
(i_stat & i_mask) gated by SR.IM2, so the sw-int was never taken:
stage-2 never ran, CD INT3 stayed unacked (process_pending freezes the
completion countdown while irq_flag != 0), and the machine deadlocked
with the display disabled and SR parked at 0x101 (IM2 stripped -> all
hardware interrupts dead).
Three changes, all architectural (no per-game logic):
1. interrupts.c psx_check_interrupts(): a pending software interrupt
(CAUSE & SR & 0x0300, plus IEc) is now a deliverable source. The
fast path, the pending check, and the SR gate each consider it; the
INTC path still requires IM2, the sw path only its own IM bit.
Exception entry sets CAUSE.IP2 only when the hardware line is what
is being delivered, so a pure sw-int presents the guest-written
IP0/IP1 bits unmodified (the dispatcher discriminates its stages by
exactly these bits).
2. interrupts.c: save/restore exception_jmpbuf across delivery. The
sw-int nests inside the hardware-interrupt handler window; the
nested setjmp used to overwrite the single global jmpbuf, so the
OUTER handler's later RFE longjmp'd into the exited inner frame
(host stack corruption, SIGSEGV).
3. dirty_ram_interp.c: deliver immediately after an interpreted MTC0
to CAUSE or SR that makes a sw-int deliverable, with EPC = the
committed next pc. Hardware vectors within the next instruction;
waiting for the next block boundary opened a window in which a
second hardware IRQ re-entered the (legitimately non-reentrant)
guest dispatcher and destroyed its saved SR. precise_irq_deliverable
gains the same sw-pending condition.
Verified on SLUS-00684: boots through BIOS/logos/FMV into rendered
3D gameplay at 60 fps, SR observed at the canonical 0x40000401, CD
irq_flag acked, MDEC decoding. BIOS-only boot unaffected.
Known scope limit: compiled (static) MTC0 sites do not yet trigger the
immediate check; the raising writes observed in the wild live in the
BIOS-installed, dirty-RAM-interpreted trampoline, which this covers.
Remove the in-tree launcher implementation and its submodules now that game projects use recomp-ui for launcher support.
Keep Vulkan hidden from the launcher unless a game explicitly sets [video] offer_vulkan = true, and clamp stale Vulkan settings back to OpenGL when it is not offered.

Add a small generic frame-hook surface for statically linked mod code. Mods can
register C callbacks with mod_register_frame_hook(); the runtime invokes them
after normal input sampling and before presentation/widescreen frame work.
Expose the SDL window symbol with C linkage so linked mod code can integrate
with SDL APIs such as window grab control.
Add opt-in [widescreen.cull] xclip_load_sites: a configured `lw rt,off(rs)`
loading a per-primitive X-reject bound (sltu-compared against ANDI-masked
u16 screen X) routes through psx_ws_xclip_bound() - INT32_MAX while the
margins are revealed (reject disabled; the wide-surface scissor clips the
overflow, wrapped off-left u16 coords pass), vanilla value at 4:3. Matched
native codegen emit and interpreter hook; overlay ABI v18 forwarder (NULL
preserves the vanilla loaded value); codegen ver 8. Parser, codegen and
overlay-mismatch regression coverage.
Split from #49: replaces the xclip_globals RAM poke with a recompile-time
instruction transform so native shards and the interpreter behave identically.
Add opt-in [widescreen.cull] plane_nx_sites: a configured `lw rt,off(rs)`
loading the X component of a side frustum-plane normal (sign-tested per
corner, dot = nx*px + nz*pz) routes through psx_ws_plane_nx() — scaled by
the inverse aspect factor (4*den)/(3*num) while the margins are revealed,
widening the plane cone by exactly atan((3*num)/(4*den)*tan(theta));
identity at 4:3. Matched native codegen emit and interpreter hook; overlay
ABI v17 forwarder (NULL preserves the vanilla normal); codegen ver 7.
