The sidebar "+" now stacks a tab instead of replacing the surface, so the
prior session stays mounted and several chat surfaces can be on the page at
once. Helpers that waited for the old transcript to disappear from the page
timed out, and `.first()` locators / bare `document.querySelector` calls
started resolving against the wrong session (CI's "resolved to 2 elements"
strict-mode violation).
Target the most recently mounted `[data-composer-target]` surface instead,
and assert the NEW surface is empty rather than waiting for the old text to
vanish.
Update the gateway's live turn projection after an accepted correction so a warm session resume does not add the stale original prompt beside the persisted correction.
Cover the inference-time correction path end to end and assert both redirect entry points refresh the live user text.
* test(desktop): cover correction resume without duplicate prompts
Exercise a live composer correction, switch away and back before the
response settles, and assert both user turns retain their order and occur
exactly once.
* test(desktop): cover correction warm resume during tool run
Exercise a correction accepted at a foreground-tool boundary, a switch through a persisted session, and the warm resume back. Assert the original prompt and correction remain singular and ordered.
