fix: copy source files from fix/node24 for correct import type keywords

Node 24 native TS requires explicit `import type` for type-only imports.
Copy all source .ts files from fix/node24 which have the correct type
keywords. Restore parse5 v6 types for files with DefaultTreeAdapterTypes.
Fix package subpath imports (.ts -> .js for @web/* package imports).
Fix extractModulesAndAssets type mismatch.
