PR #1311: Replace separate spaceWidth + getSpaceKernAdjust() with a single getSpaceAdvance() that combines space glyph advance and kerning in fixed-point before snapping to pixels, eliminating +/-1 px rounding drift in text layout. PR #1322: Add early exit to fillUncompressedSizes() once all target entries are matched, avoiding unnecessary central directory traversal. Also updates tracking docs and verifies PR #1329 (reader utils refactor) matches upstream after merge. Made-with: Cursor
