fix: add missing svelte-eslint-parser dependency

[braden-w]

Adds the missing svelte-eslint-parser package to devDependencies. This package is imported in eslint.config.js but was not listed in package.json, causing the quality check to fail with Cannot find package 'svelte-eslint-parser'.

Changes:

• Added svelte-eslint-parser@^1.4.0 to devDependencies in package.json
• Updated bun.lock

This fixes the quality check failure seen in CI.
