* Automated Git Hooks PoC (Gen 2 - Production Tooling)
|
|
*
|
|
* This script proves that we can hook into Git's native events to automatically
|
|
* generate code intelligence graphs. It creates a temporary Git repository,
|
|
* writes a real bash script to `.git/hooks/pre-commit`, and triggers a commit.
