docs(docs): merge API reference into one page

[Octane0411]

Why

The API Reference was split across multiple pages, but we want a Claude-style single-page reference flow for faster scanning and easier onboarding.

Also, the docs site lacked a clear global footer with official brand links.

What Changed

1) Consolidated API docs into one page

• Merged function, lifecycle, types, and tool I/O sections into:
  • /api-reference/overview/
• Added in-page section anchors for quick navigation.

2) Updated docs entry links

• Updated docs homepage API cards/links to point to the single API page anchors instead of split routes.

3) Navigation alignment

• Sidebar keeps a single API entry under Reference:
  • API Reference -> /api-reference/overview/

4) Added a global docs footer with brand links

• Added a custom Starlight Footer component override.
• Footer now includes:
  • Official Website: https://oasai.studio/
  • X: https://x.com/OasAIStudio
  • GitHub: https://github.com/OasAIStudio/open-agent-sdk

Files Changed

• packages/docs/src/content/docs/api-reference/overview.mdx
• packages/docs/src/content/docs/index.mdx
• packages/docs/src/components/Footer.astro
• packages/docs/astro.config.mjs

Validation

• bun run docs:build (pass)

Scope

• Documentation-only change.
• No runtime/package API behavior changed.
