theme_converter: strip @media blocks, fix doc comments, add tests

Strip @media blocks before CSS parsing to prevent high-contrast
overrides (e.g. color: highlight) from leaking into token styles.
Skip asterisk separator comments in extractDescription and fall back
to filename-derived descriptions for themes without doc comments.

Extract converter logic into src/converter.js for testability and add
49 unit tests covering all exported functions.- restore registry, update docs and examples for new languages
The prism_converter tool was overwriting the registry with only the
languages converted in each run. Fix the tool to always include all
known languages in the registry. Regenerate the registry with all 36
languages, update language counts and tables in README, docs, and
smalto.gleam module doc. Add extension mappings for the 6 new languages
(C#, F#, Nginx, Razor, React JSX, React TSX) to dev/cat.gleam.- escape lone curly braces in JS regex compilation
JS unicode mode (u flag) requires { and } to be escaped when not
part of valid quantifiers, unlike PCRE which treats them as literals.
This caused C#/Razor grammar regexes (e.g. with(?=\s*{)) to silently
fail to compile on the JS target, dropping keyword and class-name rules.
