Extract platform-specific install logic from monolithic installer functions
into small, focused helpers. Both functions had nested OS/package-manager
cascades (depth 3-4) that made the control flow hard to follow.
ensure_jq (shared/common.sh):
- Extract _install_jq_brew, _install_jq_apt, _install_jq_dnf, _install_jq_apk
- Extract _report_jq_not_found for the fallthrough error message
- Main function becomes a clean dispatcher + verification
ensure_gh_cli + _install_gh_binary (shared/github-auth.sh):
- Extract _install_gh_brew, _install_gh_apt, _install_gh_dnf
- Extract _detect_gh_platform, _fetch_gh_latest_version, _download_and_install_gh
- _install_gh_binary drops from 71 to 12 lines as a clean orchestrator
- ensure_gh_cli drops from 57 to 29 lines
No behavior changes. All tests pass, bash -n passes.

Standalone, sourceable script that installs the gh CLI and runs
interactive gh auth login. Any agent script on any cloud can source
it and call ensure_github_auth to get authenticated with GitHub.
- ensure_gh_cli: installs via brew/apt/dnf/binary fallback
- ensure_gh_auth: uses GITHUB_TOKEN or interactive OAuth flow
- ensure_github_auth: combined convenience wrapper
- Idempotent, macOS bash 3.x compatible, curl|bash compatible
