v1.59.0 - Maintenance release

Breaking changes

libtmux 0.50.0 (#996)

libtmux minimum version bumped from 0.49.0 -> 0.50.0.

Internal updates to use libtmux's new unified options API:

• Session.attach_session() → Session.attach()
• Window.show_window_option() → Window.show_option()
• Window.show_window_options() → Window.show_options()
• Window.set_window_option() → Window.set_option()

Note: Options now return Python-native types (True/False instead of
"on"/"off", int instead of numeric strings).
