v0.5.182

What's new

• Spawned agents now default to Opus 5. The orchestrator brief and the
  orchestra-spawn skill previously told agents to "leave implementation on a
  cheaper tier" to conserve swarm tokens, so spawning agents routinely pinned
  workers to Sonnet on their own initiative. Both now direct spawns to pass
  --model opus unless you explicitly ask for a cheaper tier — the
  cost/capability trade is yours to make, not the spawning agent's.

  (No code ever hardcoded Sonnet: an unset model inherits your login default.
  It was the guidance that steered agents to override it.)
