Mission context was buried at the end of a 21K char system prompt and the
agent ignored it. Two fixes:
1. Mission block now emits FIRST in build_runtime_prompt() so it's the most
prominent instruction the agent sees
2. When an active mission exists and no user prompt is given, auto-inject
an initial user message triggering the agent to read mission state files
