Windows-compat hardening across every branch to reach 100% on the seedgo standards audit: - UTF-8 stdout/stderr reconfigure guards (getattr form) on Rich/CLI entry points - platform-branched POSIX-only subprocess kwargs (start_new_session -> CREATE_NEW_PROCESS_GROUP on win32) - seedgo windows_compat checker: credit the getattr reconfigure form + locking test - commons: shared-init test-suite speedup - spawn: aipass_framework template — strip pytest.ini inline comments + add scaffold smoke test - includes in-progress cross-OS testing work (doctor/init_flow/cross_os handlers + tests) Verified: full audit 17/17 at 100%, pyright clean.
