Pull Request Overview
This PR modifies how TypeScript library files are referenced in build info (tsbuildinfo) files by encoding only the library file name instead of its full path. This change reduces the file size of build info files and makes them more portable across different environments.
Key changes:
- Library file names in build info are shortened from full paths like
"../../../../tslibs/TS/Lib/lib.esnext.full.d.ts"to just filenames like"lib.esnext.full.d.ts" - Build info file sizes are correspondingly reduced by 20-26 bytes per file

Should there be some special naming moniker to indicate that these paths are sanitized in some way? Or is it the case that fileNames is always relative paths and so this naming is okay?

Yes the fileNames are relative to buildInfo so should be ok imo .. if need arises we can probably add some special character in the beginning to identify them
