Subject: [PATCH] fix(export): split bulk-export toast across success / partial
 / all-failed
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The Phase 9 bulk export utility had a single success toast that was emitted
even when zero of N writes succeeded — "Exported 0 of 5 transcripts to
folder/" reading like the user just deliberately exported nothing.

Branch on the result count:
- 0 of N: error toast pointing at the console for write failures.
- N of N: success toast.
- M of N: warn toast — partial export, with the same console pointer.

Single-file save (`saveTranscriptAsMarkdown`) was already correct:
explicit success on save, error on failure, silent on user-cancelled —
left untouched.
