Fix proxy authentication flows by adjusting bare server rate limiting

[Copilot]

The bare server rate limiting was blocking legitimate authentication flows for reCAPTCHA, Cloudflare verification, and Google Sign-in due to overly aggressive connection throttling.

Changes

Server Configuration (server/index.ts)

• Increased windowDuration 10s → 60s to accommodate OAuth handshakes
• Removed validateConnection function that incorrectly rejected keepalive connections
• Set filterRemote: undefined to allow authentication service endpoints

const bareServer = createBareServer("/bare/", {
    connectionLimiter: {
        maxConnectionsPerIP: parseInt(process.env.BARE_MAX_CONNECTIONS_PER_IP as string) || 500,
        windowDuration: parseInt(process.env.BARE_WINDOW_DURATION as string) || 60,
        blockDuration: parseInt(process.env.BARE_BLOCK_DURATION as string) || 30,
    },
    filterRemote: undefined
});

Documentation

• Added AUTHENTICATION.md documenting built-in Ultraviolet/Scramjet support for authentication flows
• Updated README.md with authentication capabilities and configuration defaults

Technical Context

Ultraviolet includes native CAPTCHA/OAuth support via proper iframe handling, CORS headers, and cookie management. The issue was server-side, not client-side - authentication flows require multiple rapid requests that were being rate-limited out.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• telemetry.astro.build
  • Triggering command: node /home/REDACTED/work/Radius/Radius/node_modules/.bin/astro build (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

Original prompt

fix the proxy systems to alow for recaptia and cloudflare varaficaition, as well as google sign in support but be shure to keep all of the core functions and fetures in tacked
