gateway/status.py grew past main's size (code-health FILE_LINES). Move the
cohesive `python -c <src>` parsing group -- inline_source_flag_index,
command_line_runs_inline_source, the Hermes bootstrap patterns,
_bootstrap_entry and inline_bootstrap_argv -- verbatim into the new sibling
gateway/status_inline_source.py (no imports of the facade, so no cycle).
status.py imports the three names it uses; the one external caller
(hermes_cli/update_cmd_windows.py) now imports from the sibling. No shim,
no docs named the symbols. Behaviour unchanged.
