feat: give the creative trunk an outward aperture and the right to think

The watch proved the creative trunk fired (~14 discovery cycles
overnight, many genuinely task-free) but produced zero creation —
no artwork, no essay, just `no action` or maintenance tooling. Two
causes, both fixed here.

1. No outward perception. Kuro's senses are all its own machine, so
   "perceive what should exist" only ever yields a bug detector.
   The creative-trunk prompt now restores Alex's earliest approach:
   freely explore the web — art, design, music, maths, nature,
   anything genuinely interesting, no work constraint — form your
   own ideas, then make something. Curiosity needs the world as
   material.

2. The cloud-token governor starved it. decideCloudTokenRoute threw
   discovery cycles to deterministic-probe (no LLM) on a 6h
   cooldown, an open-cycle sub-budget, and a noop-streak gate — so
   ~5 of every 6 creative-trunk cycles could not even think. You
   cannot create with a code probe. Discovery now gets call-cloud,
   bounded only by the daily hard token budget; the cooldown /
   sub-budget / noop gates are removed for the creative trunk.

A primary trunk gets to look outward and gets to think. Typecheck
clean; cloud-token-governor tests updated and passing (6/6).
