doctor: detect IBus/GTK misconfigurations that break input (#572)
* doctor: detect IBus/GTK misconfigurations that break input (#550) Adds _doctor_check_im_modules helper covering the four input-method failure modes from #545: - ibus-gtk3 package missing while GTK_IM_MODULE=ibus - GTK immodules cache stale (active module not listed by gtk-query-immodules-3.0 --update-cache fixes it) - XWayland session routing IBus through XIM (lossy for some IMEs; informational note pointing at CLAUDE_USE_WAYLAND=1 for native Wayland IME) - CLAUDE_GTK_IM_MODULE override visibility (informational, so users can verify the resolved value) Each check is gated so it only fires when relevant — e.g. the package check is skipped when GTK_IM_MODULE isn't ibus, the cache check is skipped when gtk-query-immodules-3.0 isn't installed, and the package check returns silently on distros without dpkg/rpm/pacman to avoid false negatives. Adds tests/doctor.bats with 17 cases covering each gating branch and the _cowork_pkg_hint mapping for ibus-gtk3 (Arch maps to plain ibus since it bundles the GTK3 immodule). Hoists _distro_id resolution to the top of run_doctor so the IM check and the existing Cowork section share one /etc/os-release read. Closes #550. Refs #545, #549. Co-Authored-By: Claude <claude@anthropic.com> * doctor: simplify IM-check helper and DRY out doctor.bats setup Mechanical clean-up of the #550 diff after self-review: scripts/doctor.sh - tighten the _doctor_check_im_modules docblock: drop the "each check is gated" paragraph (self-evident in the code) and inline the XWayland/XIM rationale into the failure-mode bullet - drop the inline section comments that just restated the next block's purpose; keep the rc=1/rc=2 comment because the value distinction is the load-bearing detail - replace the `local _pkg_rc=0; ... || _pkg_rc=$?; if ((_pkg_rc == 1))` dance with a `case $?` on the direct call tests/doctor.bats - hoist the `command -v gtk-query-immodules-3.0 → not-found` shim into a `_skip_gtk_query` helper (it was duplicated across 11 of the 17 cases) - default `_pkg_installed() { return 2; }` in setup so per-test stubs only appear when the test cares about rc=0 or rc=1 - drop dead `_skip_gtk_query` calls from cases where the function returns earlier (no IM selected, package warn fires) so the shim is only present where it actually changes behaviour No behaviour change — all 17 doctor.bats cases still pass, plus the 68 launcher-common.bats cases. Shellcheck is unchanged from baseline. Co-Authored-By: Claude <claude@anthropic.com> --------- Co-authored-by: Claude <claude@anthropic.com>
