bug: rtk gh issue view -R fails outside git repo (plain gh works)

[pavelbe]

Summary

rtk gh issue view ... -R <owner/repo> fails outside a git repository with:

failed to run git: fatal: not a git repository (or any of the parent directories): .git

This breaks parity with plain gh, which works with -R from any directory.

Environment

• rtk: 0.22.0
• gh: authenticated and working
• OS: Linux (WSL2 Ubuntu)
• checked on: 19 February 2026

Reproduction

Run from a non-repo directory (e.g. /home/pavelbe/hca-system-v3):

gh issue view 185 -R rtk-ai/rtk --json number,title
# exit 0

/home/pavelbe/bin/rtk gh issue view 185 -R rtk-ai/rtk --json number,title
# exit 1
# failed to run git: fatal: not a git repository (or any of the parent directories): .git

Expected

rtk gh issue view ... -R rtk-ai/rtk should work outside git repositories, same as plain gh.

Actual

RTK path fails due to implicit git-repo dependency even when explicit -R is provided.

Impact

• breaks global/ops scripts that query GitHub from arbitrary directories,
• forces fallback to raw gh/rtk proxy gh for basic read operations.

Notes

No duplicate open/closed issue was found with queries:

• rtk gh issue view -R not a git repository
• failed to run git fatal not a git repository rtk gh
• rtk gh not a git repository

Update (19 February 2026): reproduced on rtk 0.22.1 as well. '/home/pavelbe/bin/rtk gh issue view 185 -R rtk-ai/rtk --json number,title' still fails outside git repo with 'failed to run git: fatal: not a git repository'.
