fix(javascript): parse plain TypeScript artifact dialects (#1102)

* test(javascript): reproduce TypeScript source dialect loss

Add native directory/ASAR and built public CLI owners with actual locked native TypeScript syntax/emit and independent Babel source-range oracles. Production and every workflow remain unchanged.

* test(javascript): admit isolated native compiler inputs

Use the actual TypeScript7 producer-requested --ignoreConfig flag when supplying isolated source filenames. Preserve every graph input, owning assertion, control and production file.

* fix(javascript): parse plain TypeScript artifacts without JSX

Select the plain .ts dialect using the artifact source path so valid angle-bracket assertions retain syntax-derived graph facts. Preserve existing JSX defaults and all other dialects. Document the inert artifact parser contract.
