Any runtime without a harness-specific hook API can now enforce guard rules by wrapping command execution with the new entry points: - `--check <cmd…>` — inspects the command; exits 0 (allow, silent) or 2 (deny, reason on stdout). Shell scripts can capture the reason and gate execution on the exit code. - `--exec <cmd…>` — inspects then exec-replaces this process with the command on allow; exits 2 with the deny reason on stderr on deny. Suitable as a transparent PATH-shadowing wrapper or shell alias for `git` and `gh`. Both modes use the same `dispatch()` core as the Claude Code and OpenCode adapters, so guard decisions are identical across all paths. Also adds `__main__.py` so the package is runnable as `python -m agent_guard`, and documents the new enforcement path in the README under a "Harness-neutral path (any runtime)" wiring section. Validation: all 74 agent-guard tests pass; vendor-neutrality score remains 100% (agent-guard stays portable). Generated-by: Claude (claude-sonnet-4-6)
