fix(javascript): preserve TypeScript loader and dependency semantics

Share loader selection across static findings and module relationships: CTS static imports and re-exports use CommonJS lookup while dynamic imports retain ESM lookup. Retain runtime import-equals dependencies, bindings, and exported names; do not resolve require file-URL strings as local artifacts. Restore import-map descriptions in CLI help.

Validated resolver and semantic tests, application reconstruction boundaries, and CLI help. Installed TypeScript NodeNext emission and Node require behavior were checked independently. Refs #2056, #2057, #2058, #2053.
