Fixing unit tests on windows (#813)

* Add Windows stub for orphan cleanup * Fix account switch tests on Windows * Make query session events test portable * Disable beads daemon in query session events test * Add Windows bd stubs for sling tests * Make expandOutputPath test OS-agnostic * Make role_agents test Windows-friendly * Make config path tests OS-agnostic * Make HealthCheckStateFile test OS-agnostic * Skip orphan process check on Windows * Normalize sparse checkout detail paths * Make dog path tests OS-agnostic * Fix bare repo refspec config on Windows * Add Windows process detection for locks * Add Windows CI workflow * Make mail path tests OS-agnostic * Skip plugin file mode test on Windows * Skip tmux-dependent polecat tests on Windows * Normalize polecat paths and AGENTS.md content * Make beads init failure test Windows-friendly * Skip rig agent bead init test on Windows * Make XDG path tests OS-agnostic * Make exec tests portable on Windows * Adjust atomic write tests for Windows * Make wisp tests Windows-friendly * Make workspace find tests OS-agnostic * Fix Windows rig add integration test * Make sling var logging Windows-friendly * Fix sling attached molecule update ordering --------- Co-authored-by: Johann Dirry <johann.dirry@microsea.at>
