Fix glyph cache poisoning across renders; add CLAUDE.md and handoff.md

Browse Source 
fontkit caches glyphs per font for the whole process and pdfkit embeds composite
components with no code points, so setting ':' before '.' in Poppins corrupted every
later render in the same process (text layer showed '1,200;00', line breaks shifted).
primeFontGlyphs() now creates the component glyphs with their cmap code point at font
registration, awaited by renderCore and browser init. Regression test and Quirk 13 added;
the warm-up workarounds in the template tests are removed.
