Use posix_spawn on hosted Linux and Darwin. Map process files, apply the working directory and process group, and clear the child signal mask. Use wait4 for process status and support Kill and Signal. Mark Darwin pipes close-on-exec under ForkLock. Darwin also needs the fcntl wrapper in PR tinygo-org#5612 and the libSystem symbols in PR tinygo-org#5636. Concurrent spawn and pipe creation need the RWMutex fix in PR tinygo-org#5630. Keep the process stubs on other targets and add process regression tests.

Validation is consolidated in #18, which includes the declared process prerequisites. Running this branch alone on Darwin would only reproduce the known missing dependencies. The upstream PR remains separate and open. |

Validation only for tinygo-org#5634. Darwin has explicit prerequisites tinygo-org#5612 and tinygo-org#5636 which are not copied into this branch. A Darwin link failure without those prerequisites is expected. This fork PR will not be merged.
