"new" in root ctl now accepts optional key=value pairs in any order:
backend=<name>, model=<name>, agent=<name>. All are optional; omitting
any uses the default. Replaces the old positional backend/agent args.
Unknown keys and malformed entries are rejected with a clear error.

Exposes the active model name as a readable/writable file. Initialized
from be.Model() at session creation. Writes submit "/model <name>" via
the agent core and update modelName optimistically, rolling back on an
error event.
