/**
 * adapters/antigravity — Google Antigravity platform adapter.
 *
 * Implements HookAdapter for Antigravity's MCP-only paradigm.
 *
 * Antigravity hook specifics:
 *   - NO hook support (MCP-only, same as Codex CLI)
 *   - Config: ~/.gemini/antigravity/mcp_config.json (JSON format)
 *   - MCP: full support via mcpServers in mcp_config.json
 *   - All capabilities are false — MCP is the only integration path
 *   - Session dir: ~/.gemini/context-mode/sessions/
 *   - Routing file: GEMINI.md (shared with Gemini CLI filename, different content)
 *
 * Sources:
 *   - Config path: https://github.com/google-gemini/gemini-cli/issues/16058
 *   - MCP support: https://antigravity.google/docs/mcp
 *   - Tool list: System prompt leak (21 verified tools)
