Cmux typically does not set TERM_PROGRAM; it sets LC_TERMINAL=Cmux instead.
The previous resolve_method() only checked TERM_PROGRAM, causing Cmux users
to fall back to the Bel method instead of OSC 9 notifications (#1281).
Changes:
- Add LC_TERMINAL as a secondary env-var probe in resolve_method(), checked
after TERM_PROGRAM. This picks up Cmux (and any other OSC-9 capable
terminal that sets LC_TERMINAL rather than TERM_PROGRAM).
- Add Cmux to the OSC9_TERMINALS allowlist.
- Document that terminals setting neither env var can force OSC 9 with
[notifications].method = "osc9" in the config file.
- Add two new tests:
- auto_detect_picks_osc9_for_cmux_via_lc_terminal
- auto_detect_picks_osc9_for_wezterm_via_lc_terminal
- Harden existing auto_detect_picks_bel_for_unknown_on_unix to clear
LC_TERMINAL before asserting the Bel fallback, preventing flakiness in
test runner environments where LC_TERMINAL is set to a known terminal.
- Update NotificationsConfig.method doc to mention Cmux and the
LC_TERMINAL probe.
