Port three new upstream commits and align the existing #1002 port:
- PR #1014: Strip unused CSS rules by filtering unsupported selector
types (+, >, [, :, #, ~, *, descendants) in processRuleBlockWithStyle.
Fix normalized() trailing whitespace to also strip newlines.
- PR #1018: Add deleteCache() to CssParser, move CSS_CACHE_VERSION to
static class member, remove stale cache on version mismatch, invalidate
section caches (Storage.removeDir) when CSS is rebuilt. Refactor
parseCssFiles() to early-return when cache exists.
- PR #990: Adapt classic theme continue-reading card width to cover
aspect ratio (clamped to 90% screen width), increase homeTopPadding
20->40, fix centering with rect.x offset for boxX/continueBoxX.
- #1002 alignment: Add tryInterpretLength() to skip non-numeric CSS
values (auto, inherit), add "both width and height set" image sizing
branch in ChapterHtmlSlimParser.
