Deno + Tailwind4 + TS update

[sakgoyal]

• Migrate to tailwind 4 (Automatic migration from codemod)
• Fix many typescript issues
• Use Deno instead of Node
  • Removes many dependencies
  • simplifies workflow
  • remove many config files
  • Ran formatter (reordered imports)
    • enforce proper file extensions in imports
  • Import map to simplify imports
  • prefix node api imports with node:
• Update dependencies

Issues:

• Deno fmt
  • does not support disabling trailing commas
  • does not support folder specific options (.tsx specific options), or maybe I just dont know how
• react-tag-input does not properly export types
  • need to do annoying import in TagList.tsx

TODO:

• see if import maps can remove the need for specifying "index.ts" in imports somehow
