fix(github): add augmented PATH env to all gh CLI calls

When running from a packaged macOS app (.dmg), the PATH environment
variable doesn't include common locations like /opt/homebrew/bin where
gh is typically installed via Homebrew.

The getAugmentedEnv() function was already being used in some places
but was missing from:
- spawn() call in registerStartGhAuth
- execSync calls for gh auth token, gh api user, gh repo list
- execFileSync calls for gh api, gh repo create
- execFileSync calls in pr-handlers.ts and triage-handlers.ts

This caused "gh: command not found" errors when connecting projects
to GitHub in the packaged app.
