The default command dispatches to sessions by calling sessionsCommand.run
with a hand-rolled context. After 0.3.1 added --json, sessions started
reading ctx.values.json — which threw on the fake { args: {} } context
because values was undefined.

Pass { values: {} } instead so the property lookup resolves to undefined
(then the existing ?? false fallback handles it).

Release v0.3.2.
