Enable the live planning test against claude-haiku-4-5

The virtual key now reaches a Haiku-class route, which holds the
tool-call contract llama3.2 could not: a real planning turn returns a
well-formed submit_plan call with an explicit, low-inference plan.

Wires NISSE_LIVE_PLANNER_MODEL through the CI workflow (add the
matching Actions secret to run it there) and records the finding in
.env.example.
