fix(manifest): extract TS adapter args at build time for proper CLI registration

The manifest builder now statically parses TS source files to extract
args, description, columns, domain, and strategy metadata. Previously
TS adapters had empty args in the manifest, causing commander to reject
their options (e.g. --keyword) before the lazy module could load.

Also includes the xiaohongshu search DOM fallback fix from earlier.
