Slice 3: Expedition Combat Spine — epoch-seeded zone waves (DR-040)

Browse Source 
Reactivate the dormant Expedition region as a procedural combat venue.
v1 loop: walk the gate -> fight an epoch-seeded enemy wave in the
expedition -> clear -> return -> flat Ore reward (once per epoch) ->
escalated retaliation base siege.

- New sim types: ZoneEnemyTag, ZoneEnemyDirector (+ ZoneEnemyPrefab
  buffer), ZoneEnemyState, ZoneEnemyMath (grunt->charger composition
  by epoch). ZoneEnemyDirectorSystem (server, Burst): drip-spawns the
  wave at a deterministic ring under a MaxAlive cap while a player is
  out and the base is Calm; marks ClearedThisEpoch on a real clear.
  [UpdateAfter(ExpeditionFieldSystem)] only (avoids a sort cycle).
- BLOCKER 1: EnemyAISystem region-filters target selection (player +
  structure snapshots gain parallel region lists; no base structures /
  no Core fallback for expedition husks).
- BLOCKER 3: WaveSystem, ThreatDirectorSystem timeout cull, and
  CyclePhaseSystem DefendCleared + Core-breach cull all count/cull
  RegionTag{Base} husks only (the breach cull was caught region-blind
  by the post-impl review: a base breach wiped the live expedition
  wave and spuriously paid the reward).
- BLOCKER 4: reward de-duped via CycleRuntime.LastRewardedEpoch +
  ClearedThisEpoch; ExpeditionGateSystem deposits RewardOre once/epoch.
- ExpeditionFieldSystem teardown also culls zone enemies + region-
  guards the clutter loop. Subscene wired with the director + roster.

368/368 EditMode green + clean netcode Play smoke. Docs: DR-040 ->
built, session log, CLAUDE.md cross-region tag-reaudit rule.

/// <summary>
/// Server-only expedition zone-enemy director: while a player is OUT in the expedition region and the base is in
/// <see cref="CyclePhase.Calm"/>, it seeds and drip-spawns one epoch-seeded combat wave around the expedition
/// origin. The wave size + grunt/charger composition is pure <see cref="ZoneEnemyMath"/> of the
/// <see cref="CycleRuntime.ExpeditionEpoch"/> (grunt-heavy -&gt; charger-heavy as the epoch climbs), spawned one
/// every <see cref="ZoneEnemyDirector.SpawnIntervalTicks"/> at a deterministic ring, capped at
/// <see cref="ZoneEnemyDirector.MaxAlive"/> concurrent (the v1 ghost-relevancy budget). Each enemy is the
/// existing Husk ghost prefab + <c>RegionTag{Expedition}</c> + <see cref="ZoneEnemyTag"/>, so it reuses the whole
/// combat/readability/AI stack (the per-region AI filter keeps it seeking the expedition player only). When the
/// wave is fully spawned and every zone enemy is dead, it marks <see cref="CycleRuntime.ClearedThisEpoch"/> once —
/// the gate's once-per-epoch Ore reward reads that on the player's return.
///
/// Ordering: <c>[UpdateAfter(ExpeditionFieldSystem)]</c> ONLY. ExpeditionFieldSystem is itself
/// <c>[UpdateAfter(CyclePhaseSystem)]</c>, so ALSO declaring <c>[UpdateBefore(CyclePhaseSystem)]</c> here (as the
/// v1 plan first sketched) would close a CyclePhase-&gt;Field-&gt;Zone-&gt;CyclePhase sort cycle that throws at Play
/// world creation and is invisible to EditMode. Running after the field manager also reads the freshly-bumped
/// epoch + current phase. Zone enemies are interpolated ghosts, moved server-only — no prediction.
