Subject: feat(theme-selector): add browser-based theme design tool

A self-contained tool for building Emacs color themes by eye. generate.py emits one HTML page with six languages of tree-sitter-tokenized code, a category-to-color assignment table, a UI-faces table, and an editable palette. Reassign colors from the palette, toggle weight and slant per category, set foreground and background per UI face, then export a theme.json a later build step turns into theme files.

The export carries the name, palette, syntax assignments, bold and italic sets, and a ui object of per-face foreground and background. The theme name is both the json name field and the download filename.

samples.py holds the language samples and the default color map. theme-selector.html is the generated output. The json-to-theme converter is the next piece, and the part worth TDD.
