This PR updates the @-mention autocomplete behavior to match the web app.
When a user backspaces inside a formatted mention (e.g.
@**Chris Bobbe**),the autocomplete is now reopened by stripping the formatting and re-evaluating
the mention query, instead of suppressing autocomplete entirely.
As part of this change:
before matching.
inside formatted mentions.
autocomplete UI, which is now unmounted when no valid intent exists
instead of remaining visible with empty results.
pending timers at teardown.
Screenshots attached show the behavior before and after this change.
Before: Backspacing inside a formatted mention does not reopen autocomplete.

After: Autocomplete reopens correctly, matching web behavior.

Fixes #1967
