Type-safety, sourcemaps, and glob fixes

Preserve sourcemaps for optimized deps with follow-up transforms (1298951)

Vite now writes optimized dependency bundles with hidden sourcemaps and reads the generated .map file back when serving them. This should keep stack traces and debugging accurate even when optimized deps go through extra transforms.

Add more precise importGlob typing for known queries (cc39e55)

The importGlob types now distinguish known query values like ?raw from unknown ones, and export the new KnownQueryTypeMap. That makes the return type better reflect eager, as, and query combinations, improving type inference for users.

Fix import.meta.glob common-base detection by path segment (eb12604)

getCommonBase() no longer treats path prefixes as shared directories, so patterns like /a/foo/*.js and /a/foobar/*.js correctly resolve only to /a. This avoids incorrect base calculation when glob roots merely share a string prefix.

Other misc changes

• Bumped es-module-lexer to 2.0.0.
• Clarified loadEnv() docs to say it merges matching process.env values.
