Fix Windows platform test failures

- bash.py: Add sys.platform check before os.set_blocking() call
- test_filesystem.py: Use platform-specific Glob implementations (GlobWindows/GlobMac)
- test_filesystem.py: Move Windows skip inside test method for unreadable file test
- test_planmode.py & test_filesystem.py: Use component-based path assertions instead of exact matches
- test_session.py: Use component-based path resolution checks
- test_tui_input.py: Make tilde completion assertions case-insensitive

All fixes preserve exact behavior on Linux/macOS while enabling Windows compatibility.
