refactor: replace pastel-wasm with pure TypeScript color engine

Removes the @valknarthing/pastel-wasm WASM dependency and replaces it
with a self-contained TypeScript implementation of all color operations
(parsing, conversion, manipulation, gradients, palette generation).
Adds eslint-plugin-react-hooks which was missing from devDependencies.
