bun run build fails in checkGaGraph when repository is cloned into a directory named antigravity #46

Problem

In packages/opencode/scripts/build-tui.ts, checkGaGraph tests each file in graph.files against GA_FORBIDDEN_SOURCE:

const GA_FORBIDDEN_SOURCE =
  /\/(?:rpc|plugin|antigravity|hooks)\/|\/ga\/(?:server|rpc)\/|.../

Because graph.files holds absolute filesystem paths and GA_FORBIDDEN_SOURCE is unanchored, cloning the repository into a directory named antigravity (for example /workspace/antigravity) causes every file path to match /\/antigravity\// on the checkout directory segment.

Reproduction

1. Clone the repository into a folder named antigravity:

   git clone https://github.com/cortexkit/antigravity-auth.git antigravity
   cd antigravity
   bun run build

2. packages/opencode build fails immediately in checkGaGraph:

   error: graph.ga: forbidden GA source /.../antigravity/packages/opencode/src/common-auth-embedded/quota/codec.js
       at checkGaGraph (packages/opencode/scripts/build-tui.ts:165:17)
   

Fix

Slice audited file paths from the last /src/ segment before testing GA_FORBIDDEN_SOURCE so parent checkout directory names above src/ cannot trigger false positives while forbidden paths under src/ (/src/antigravity/, /src/rpc/, /src/plugin/, etc.) remain blocked.
