Drops highlight.js, lunr, autoprefixer, and @types/markdown-it —
all verified unreferenced (markdown-it ships its own types). Adds
knip.json configured for the templ/htmx architecture: main.ts and
reader/reader.ts entries, vitest tests as entry points, and an
ignore list for the ten modules whose exports are bound by templ
Alpine attributes — string bindings that static analysis cannot see.
