A generic callback's T took in the closure's captures (a 1-in-4 tslang crash)

this.particles.filter((particle) => ... this.lifetime) in a class method: while the method's return type is discovered, the arrow's type is rebuilt with its captures as its first input. Inference dropped that input only for an arrow already bound (#738), not on this first pass, where it is still a bare generic reference, so T became FlameParticle | captures. The union's members are ordered by their types' addresses: when the captures came first the arrow's parameter was taken for them, and tslang crashed (0xC0000005; "Invalid index!" in mlirGenFunctionParams in a debug build) in about one run in four on native_ts_graphics' core/ray_tracing_extended_scene.ts — which broke its default build at random. pre-alpha111 built locally crashes too; its release binary happened not to. instantiateSpecializedFunctionTypeHelper now reports whether the type it built has captures first, and inference drops them in either case. Scene file: 0/30 crashes (was ~8/30).

Test: tests/00generic_callback_closure_late_class.ts — its own generic keep<T>, the element class declared later in the file, which makes the bug deterministic (pre-alpha112: "cast from array type ... to array type '!ts.array<!ts.union<..., !ts.ref<!ts.tuple<{"this",...'"). gc, and rc/none through the corpus.

Also

• Anonymous function names hash the file's name (xxh3), not the StringAttr's storage address: ..afL89C49FH<hash> was different in every run.
• LLVM::registerInlinerInterface in createMLIRContext: a debug tslang ended every --emit=jit with "checking for an interface (mlir::DialectInlinerInterface) that was promised by dialect 'llvm' but never implemented".
• .gitignore: __jit*/ (the debug JIT cache folder too).

Found, not fixed (pre-alpha112 has them too), each with a class declared later in the file than its use:

• the built-in arr.filter(arrow) (--no-default-lib): "the condition has no value";
• a field of it read in main when main also calls assert(...): "Can't resolve property 'duration' of type any" (print of the same expression works).

Release ctest: 6578/6578. native_ts_graphics default build with this compiler: complete; basic_triangle runs, also under the JIT (release and debug tslang).
