…DE.md rule #5) stage1 self-compiled binary crashed on Array.isArray because inserting a new field mid-class shifted GEP indices for subsequent fields (most notably lastInlineLambdaEnvPtr in BaseGenerator, although the same rule applies to LLVMGenerator's own fields). moving trampolineEmitter to the END of both IGeneratorContext and LLVMGenerator's field lists restores the expected struct layout and unblocks stage2 self-hosting.

…PR2 of closure-cabi series) (#564) * feat(runtime): wire closures to child_process.spawn via trampolines, remove spawnTagged (pr2 of closure-cabi series) arrow-function callbacks now work with child_process.spawn(). captured variables are lifted into a gc-allocated env struct, registered with the trampoline slot table (pr1 infrastructure), and dispatched through a per-shape trampoline that the c bridge invokes after recovering env via cs_tramp_get(handle). this removes a long-standing constraint that spawn callbacks had to be named function references. multi-session demuxing (formerly spawnTagged, which is hard-removed here) is now a natural capture: child_process.spawn(cmd, args, (d) => onOut(sessionId, d), (d) => onErr(sessionId, d), (c) => onExit(sessionId, c)) changes: - c_bridges/child-process-spawn.c: cs_spawn_v2 takes per-callback {fn_ptr, tramp_handle} pairs. handle == -1 keeps the legacy bare-fn path; handle >= 0 routes through the trampoline. slots freed in the pipe-close / post-exit callbacks. - src/codegen/stdlib/child-process.ts: spawn() accepts arrow functions alongside variable refs; generates trampoline env + cs_tramp_alloc. - src/codegen/infrastructure/trampoline-emitter.ts: instantiated on the llvm generator, emitAll() called after lifted lambdas. stores user fn as i8* to sidestep the store-type validator. - chadscript.d.ts, llvm-declarations.ts: spawnTagged and cs_spawn_tagged removed. spawn signatures updated to document closure support. - src/codegen/expressions/method-calls/named-object-dispatch.ts: emits a clear compile error if anyone still calls spawnTagged. - tests/fixtures/closures-cabi/: three new fixtures cover single-session closure capture, multi-session demux, and named-fn back-compat. - tests/fixtures/builtins/cp-spawn-tagged.ts removed (closure form subsumes it). * fix(codegen): move trampolineEmitter to end of class field list (CLAUDE.md rule #5) stage1 self-compiled binary crashed on Array.isArray because inserting a new field mid-class shifted GEP indices for subsequent fields (most notably lastInlineLambdaEnvPtr in BaseGenerator, although the same rule applies to LLVMGenerator's own fields). moving trampolineEmitter to the END of both IGeneratorContext and LLVMGenerator's field lists restores the expected struct layout and unblocks stage2 self-hosting. --------- Co-authored-by: cs01 <cs01@users.noreply.github.com>
