chore: migrate to esbuild tooling and update Pyodide to 314.0.7

Align the build with the official Acode plugin template and fix Python
failing to load on some devices.

Tooling:
- Replace webpack/babel/postcss/sass with esbuild (dev server on :3000)
- Restore pack-zip.js at the repo root (webpack config imported a moved file)
- Copy the Pyodide runtime from npm into dist/lib on every build; dist/lib
  had been dropped from git, so clean builds shipped without Python
- Add tsconfig for acode-plugin-types, Biome dev dependency and check script
- Replace JSX with tag() calls and SCSS with plain CSS

Pyodide:
- Update to 314.0.7 (Python 3.14); run the worker as a module worker
- Bundle the Pyodide loader into worker.js so .mjs MIME types do not matter
- Fall back to ArrayBuffer wasm compilation when .wasm is not served as
  application/wasm, which otherwise hung on "loading..."
- Load packages on demand from the matching jsDelivr CDN (numpy, micropip...)
- Route stderr correctly and show clear load errors with retry on next run

Also bump to 1.2.0, add contributor, fix plugin.json main path.
