feat(stdlib): add fs_*/env_args/format builtins + my-cli argv forwarding#10
Merged
Conversation
Six new stdlib builtins for tooling workloads:
- fs_write_file / fs_read_file / fs_create_dir_all / fs_exists
- env_args (host-supplied with std::env::args().skip(1) fallback)
- format (positional {} substitution, {{ }} escapes)
Plus PROGRAM_ARGS OnceLock + pub fn set_program_args, and my-cli's Run
subcommand grows a trailing_var_arg field forwarded to set_program_args.
Validated by an end-to-end run of an out-of-tree scaffold tool against
six idaptik-port component repos.
See PR body for details and open design questions.
