[BUG] opencode github install - "Could not find git repository" in valid git repo

[PrakharMNNIT]

Description

The opencode github install command fails with the error "Could not find git repository" even when executed from inside a valid git repository where git status works correctly.

The .git directory exists, all git commands work as expected, but the opencode github install command cannot detect the repository.

OpenCode version

1.1.13

Steps to reproduce

1. Navigate to a valid git repository:

   cd ~/path/to/repo
   

2. Confirm git is working:

   git status
   # Output: On branch master, Your branch is up to date with 'origin/master'.
   

3. Verify .git directory exists:

   ls -la .git
   # Shows valid .git directory with all expected contents
   

4. Run the install command:

   opencode github install
   

5. Result: Error message appears:

   ┌  Install GitHub agent
   │
   ■  Could not find git repository. Please run this command from a git repository.
