moveCursor() repositioned the cursor but never called updateAutocomplete()
or cancelAutocomplete(), unlike insertCharacter()/handleBackspace(). So an
open autocomplete picker went stale when the cursor moved: e.g. typing
`/cmd ` (argument menu open) then arrowing Left back into the command name
left the argument list showing against a `/cmd` prefix, and a Tab there
concatenated the stale suggestion onto the partial command name
(e.g. `/swarepo`).
Sync the picker at the end of moveCursor(): when a picker is open, re-query
via updateAutocomplete(), which refreshes the list for the new cursor
position or closes it when nothing matches.
Adds a regression test in test/editor.test.ts (verified to fail without the
fix). Fixesearendil-works/pi#5496.
Add an explicit overlay unfocus target so callers can move input to the editor or another component while overlays remain visible. Align fallback overlay focus with visual focus order and cover blocked replacement release, null targets, and multi-overlay cycling.
Preserve a focused visible overlay as the input owner across extension custom UI replacement, while letting the replacement receive and close its own input before focus is restored. Fixes#5129.
detectCapabilities previously disabled hyperlinks under tmux unconditionally. tmux re-emits OSC 8 to the outer terminal only when the attached client advertises the 'hyperlinks' feature in client_termfeatures, and strips them otherwise.
Probe the running server with 'tmux display-message -p #{client_termfeatures}' and enable hyperlinks only when the feature is listed. The probe fails closed: any error (no tmux/server, timeout, old tmux) yields false. images stays null; only the hyperlink decision changed. The probe is injected into detectCapabilities so it stays testable without spawning a process.
