Release 0.4.0

Added

• Verbose help mode — Built-in apcore options (--input, --yes, --large-input, --format, --sandbox) are now hidden from --help output by default. Pass --help --verbose to display the full option list including built-in options.
• Universal man page generation — build_program_man_page() generates a complete roff man page covering all registered commands. --help --man outputs the man page, enabling downstream projects to get man pages for free.
• Documentation URL support — set_docs_url() sets a base URL for online docs. Per-command help shows Docs: {url}/commands/{name}, man page SEE ALSO includes Full documentation at {url}. No default — disabled when not set.

Changed

• build_module_command_with_limit() and add_dispatch_flags() respect the global verbose help flag to control built-in option visibility.
• --sandbox is now always hidden from help (not yet implemented). Only four built-in options (--input, --yes, --large-input, --format) toggle with --verbose.
• Improved built-in option descriptions for clarity.
