Vite tightens import map and HTML build fixes

Build output now strips pure CSS chunk imports correctly with chunk import maps, plus HTML import detection and preload URL handling got fixes.

sapphi-red TheAlexLichter

Fix pure CSS chunk imports when chunkImportMap is enabled (sapphi-red648bd04) Vite now resolves CSS chunk names through the generated import map before replacing empty chunks, so pure CSS imports are stripped correctly in the final build output. This fixes chunk-import-map builds where CSS-only chunks could leak into emitted code.

Speed up HTML import-only detection (TheAlexLichterb5868c0) The HTML plugin replaces a backtracking-heavy regex with a token-by-token scanner for import-only module scripts. That keeps the same behavior, but avoids pathological slowdowns on large chunks.

Preserve import.meta.url in the preload helper (sapphi-redf1f90ed) The build import-analysis preload helper now keeps import.meta.url intact instead of rewriting it in a way that could affect source maps or transforms. A test update reflects the changed sourcemap output.
