Subject: [PATCH] fix(config): config writer silently dropped
 router.narration.model_id
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Every TUI config-editor save regenerates the TOML through
CorrexConfigWriter, whose [router.narration] section never wrote
model_id — one save and narration silently fell back to the main
model, queueing every narration behind slow 9B inferences (live QA:
approval narrations arrived minutes late, after the workflow had
already failed). The writer now persists it and the field is editable
in the TUI (blank clears it).
