chore: add localias configuration for npmx.test

[vinnymac]

Configures localias so developers can utilize https://npmx.test locally, which also makes it easier to test on mobile devices without having to get fancy with tunnels or wired connections.

See CONTRIBUTING.md for "Custom Local Domain" usage instructions.

📝 Walkthrough

Walkthrough

Adds Localias-based local development domain support: new .localias.yml mapping npmx.test to http://127.0.0.1:3000; new scripts/setup-local-domain.sh to detect OS, verify/install Localias, configure capabilities, manage the daemon and create the alias; npm scripts setup:local and setup:local:uninstall; Vite allowedHosts: ['.test'] in nuxt.config.ts; .gitignore entries for local certs and .localias-certs/; CONTRIBUTING.md instructions for optional local-domain setup; and knip.ts updated to ignore the localias binary.
