The MultiEdit deny rule was already dropped in the hotfix; this is task
10's follow-up half — the guard that catches the next fossil.
The claude adapter's review branch spells "cannot edit files" in the
vendor's own tool names, and that roster moves: a rule naming a tool the
installed CLI does not have is refused at startup, so the launch dies
before the agent speaks. Membership assertions could not see that
happening, so the stub-binary test now asserts each mode's flag list
literally (settings payload elided) — a deny name added or renamed shows
up as a diff a reviewer must re-verify against the installed CLI. The
run script carries the same warning where the list actually lives.
The helper drops a leaked AGENT_MODEL, since --model would otherwise
appear in an argv now compared whole; test_agent_model.py owns that flag.
