Implement window.meta (MetaScript) Runtime#14
Conversation
Introduces the MetaScript runtime (`window.meta`) providing capacity to: - Spawn child processes asynchronously (`meta.spawn`) with I/O piping. - Spawn processes synchronously (`meta.spawnSync`) using a prompt-based bridge. - Support Terminal (PTY) for interactive subprocesses. Backend implementation using POSIX APIs (fork, exec, pipe, forkpty) and GLib integration for non-blocking I/O. JS API utilizes ReadableStreams to match requirements. Includes a comprehensive meta_demo example. Platform compatibility maintained via #ifndef _WIN32 guards. Co-authored-by: yumin-chen <10954839+yumin-chen@users.noreply.github.com>

I have implemented the
window.meta(MetaScript) runtime providingspawn,spawnSync, and PTY support.Key components:
fork/execand GLib for async I/O.window.prompt()in the GTK backend to support synchronous operations likespawnSync.window.metaAPI surface, including aSubprocessclass withReadableStreamstdout/stderr.forkptyfor interactive terminal applications.Verification:
