feat(system): fix(windows): handler guard backslash path fix — all 11 __init__.py files (#304). caller_file.replace('\\', '/') normalizes Windows paths before the same-branch check. This is the actual fix for #293 which was incorrectly closed. drone is completely broken on Windows without this. (#306)

* feat(system): ci: add Windows setup test workflow — runs setup.sh + drone CLI verification on windows-latest GitHub Actions runner. Triggers on changes to setup.sh, handler __init__.py files, cli.py, or pyproject.toml. Closes the 'we never tested on Windows' gap.

* feat(system): fix(windows): SIGPIPE guard in flow.py (#301) + fcntl platform guards in trigger/config.py and watchdog/registry.py (#302) — lazy import fcntl on Unix only, no-op on Windows. inbox_lock.py already cross-platform (msvcrt). ai_mail.py already guarded (hasattr check).
