Regression of T-268's /clear mechanism. /clear deletes the transcript and
respawns with the same deterministic --session-id, but claude 2.1.177 now
tracks session ids in ~/.claude/sessions/<pid>.json (+history.jsonl) beyond
the per-project transcript clide purges, so the id reads as in-use and
claude exits 1 at startup validation. Codebase only probed <=2.1.175.
Hypothesis is strong but unconfirmed: the pane shows an opaque "code 1" and
swallows claude's stderr — capturing it is fix step 1. Filed high with
ranked fixes (mint fresh id on clear; or clean the registry; surface stderr).
