6dc67ef483 fix: wrap module script content in block scope to prevent false redeclaration errors (#308027 )

* fix: wrap module script content in block scope to isolate variables (#229357)

When multiple <script> tags exist in an HTML file, the HTML language
server concatenates their content into a single virtual JavaScript
document for validation. This causes false "Cannot redeclare
block-scoped variable" errors when <script type="module"> tags declare
variables with the same name as regular <script> tags, since module
scripts should have their own scope per the HTML spec.

Fix by wrapping <script type="module"> content in block scope delimiters
({ ... }) in the virtual document, preventing variable name collisions
between module scripts and regular scripts.

* fix: validate HTML module scripts separately

* test: cover HTML module script isolation
