- Add a hard military conquest gate (canConquer, CONQUEST_MILITARY_MARGIN=15)
enforced in applyTurnResult: a contested invasion is repelled when the
attacker's military is more than 15 below the defender's; re-claims of
unowned regions are never gated. Emits a new 'repelled' event.
- Document the soft levers in the system prompt: stability<30 + gathering
marker -> non-military takeover; economy growth/decay drives other stats.
- Emit bounded frontierMilitary (per-neighbour balance) and takeoverRisks
hints in the user payload (only when present).
- repelled outcome color (#9f1239); full unit test coverage; stub untouched.
- Bump to v0.30.0.
