[BUG]: Antigravity 2.0 does not use Codegraph tools even when the .codegraph directory exists inside the project directory

[zenwav]

Reproduction Steps:

1. Install Codegraph globally: npm i -g @colbymchenry/codegraph
2. Configure Codegraph for Antigravity: codegraph install --target=antigravity
3. Restart Antigravity and initialize a project: codegraph init -i

Expected Behavior:

Antigravity 2.0 should automatically start using Codegraph tools since the .codegraph/ directory is present in the project.

Actual Result:

Antigravity 2.0 does not use any Codegraph tools. I verified that the codegraph serve --mcp command works correctly from the command line. Also, I tested this scenario in the exact same project using Codex. When asked the exact same question, Codex successfully utilizes Codegraph tools to provide an answer.
