28165d6 (Einhander native-wide player bounds) rewrites configured
[widescreen] signed_x_bound LUI sites into psx_ws_player_x_bound(vanilla)
calls in code_generator.cpp — and that site loop runs in overlay_mode too, so
the call lands in overlay-resident code. But the shard link contract never
forwarded the symbol: any shard containing a bound site fails to LINK
(undefined psx_ws_player_x_bound) and that variant runs interpreted forever —
the same silent class as v10 gte_read_ctrl and v12 psx_rfe_mark_escape (now
loud under the shard observability suite, but still a coverage hole).
The clamp computes against the host's live widescreen state (gpu.c), so a
local copy can't work: add the ws_player_x_bound callback (appended last),
the preamble forwarder (identity fallback => correct 4:3 on a host that
predates it), and the loader init wiring. Bump the ABI to 13 so stale DLL
mixes are rejected and regenerate.
This also unblocks removing the sljit tier: sljit's emit_ws_player_x_bound
was the only other native path carrying the clamp; with the gcc shard path
forwarding it (and dirty_ram_interp already handling the site), the feature
no longer depends on sljit.
