fix: reduce E2E test flakiness — pre-warm browse, simplify ship, accept multi-skill routing

Browse E2E: pre-warm Chromium in beforeAll so agent doesn't waste turns on cold
startup. Reduce maxTurns 10→3. Add CI-aware MAX_START_WAIT (8s→30s when CI=true).

Ship E2E: simplify prompt from full /ship workflow to focused VERSION bump +
CHANGELOG + commit + push. Reduce maxTurns 15→8.

Routing E2E: accept multiple valid skills for ambiguous prompts.
