Improve build and update dependencies

Description

• Closes webpack configuration and devDependencies usage #164
• Removed redundant depencencies that were being unnecessarily installed by users using npm to install ulabel
• Updated webpack build process to properly provide both a minified (default) and unminified build (for better debugging)
  • Added package exports field with options: . (minified), ./min (minified), ./debug (unminified)
• Add test coverage for both minified and unminified builds
• Update dependencies and fix 12 security vulnerabilities

Build File	Before (v0.19.1)	After (v0.20.0)	Change	Notes
ulabel.js (unminified)	1.04 MB	2.32 MB	+1.28 MB (+123%)	Now includes webpack runtime overhead and is human-readable for debugging
ulabel.min.js (minified)	1.04 MB	1.01 MB	-0.03 MB (-3%)	Properly minified with TerserPlugin

PR Checklist

• Merged latest main
• Version number in package.json has been bumped since last release
• Version numbers match between package package.json and src/version.js
• Ran npm install and npm run build AFTER bumping the version number
• Updated documentation if necessary (currently just in api_spec.md)
• Added changes to changelog.md

Breaking API Changes

ulabel.js is now unminified. If users were importing that file directly, and want to instead use the productionized and minified version, they should switch to ulabel.min.js

Pull Request Overview

This PR modernizes the webpack build process to properly generate both minified and unminified builds, moves runtime dependencies to devDependencies (since they're bundled), and adds comprehensive test coverage for both build variants. The changes address issue #164 by reducing unnecessary installation overhead for npm users and providing better debugging support.

Key Changes:

• Enabled TerserPlugin for proper minification of ulabel.min.js while keeping ulabel.js unminified
• Moved bundled dependencies (@turf/turf, jquery, polygon-clipping, uuidv4) to devDependencies
• Added test infrastructure to validate both minified and unminified builds across unit and e2e tests

Good fix 👍

This does have the downside of adding a massive diff to every PR. Not a huge deal, although I would lean on the side of having all of the builds done as a GH Action upon merging PRs into main (which would also automate away one step of the current PR checklist).
