In support of #1380, we need to do several things to bring manifold up to UV community standards:

• Update GitHub Actions to use up-to-date versions (including Node 20)
• Check for any other references to outdated Node versions (e.g. look in package.json and any tool-related configuration files)
• Update dependencies (pay special attention to typescript/webpack) and resolve outstanding Dependabot PRs where possible.
• Replace tslint with eslint; align configuration with UV project
• Update prettier and align configuration with UV project
• Review other PRs and merge if safe/ready
• Create a "main" branch and make it the default instead of "master"
• Retarget any remaining PRs against "main" instead of "master"
• Change any references to "master" in README, etc. to "main."
• Delete the "master" branch
• Release a new version of the component
• Upgrade the component upstream in UV
