Fix docs build: override Starlight social array with required object format

[Copilot]

mylonics-styles's mylonicsStarlightDefaults returns social as an array ([{ icon, label, href }]), but Starlight 0.32 expects a Record<platform, url> object — causing the astro:config:setup hook to throw on every build.

Change

In docs/astro.config.mjs, explicitly override social after the spread to supply the correct type:

...mylonicsStarlightDefaults('Struct Frame', { github: '...', ... }),
// mylonics-styles returns an array; Starlight 0.32 requires an object
social: {
  github: 'https://github.com/mylonics/struct-frame',
},

The spread sets social to the incompatible array; the trailing explicit key overwrites it with the valid object format.

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: /home/REDACTED/work/_temp/ghcca-node/node/bin/node node /home/REDACTED/work/struct-frame/struct-frame/docs/node_modules/.bin/astro build (dns block)
• unpkg.com
  • Triggering command: /home/REDACTED/work/_temp/ghcca-node/node/bin/node /home/REDACTED/work/_temp/ghcca-node/node/bin/node --enable-source-maps /home/REDACTED/work/_temp/copilot-developer-action-main/dist/index.js (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)
