docs: add Kiro to README + site docs (and fill in Gemini/Antigravity gaps)

PR #473 added the Kiro installer target but missed updating the README
and site documentation. This sweeps both:

- README: hero H3, badges row, installer subtitle, auto-detect list,
  restart line, Supported Agents bullet list, footer tagline.
- site/: integrations.md supported-agents list, installation.md
  auto-detect + restart lines, quickstart.md installer subtitle,
  introduction.md tagline, guides/indexing.md auto-sync paragraph,
  pages/index.astro MCP feature card.

The Supported Agents section in README and integrations.md were also
already stale from PR #399 — they didn't list Gemini CLI or Antigravity
IDE. Fixed those alongside.

 CodeGraph is a **local-first code-intelligence tool**. It parses your codebase with [tree-sitter](https://tree-sitter.github.io/), stores every symbol, edge, and file in a local SQLite database, and exposes the result as a queryable **knowledge graph** — over the [Model Context Protocol (MCP)](/codegraph/reference/mcp-server/), a CLI, and a TypeScript library.
 
-It exists to make AI coding agents — Claude Code, Cursor, Codex CLI, opencode, and Hermes Agent — **answer structural questions without scanning files**. Instead of fanning out across `grep`, `glob`, and `Read` to reconstruct how code fits together, an agent queries a pre-built index and gets the answer in a handful of calls.
