feat(totalannihilation): add victory conditions, new defensive towers, and combat improvements 

- Introduce configurable victory modes: "commander" (default, kill enemy commander) and
  "annihilation" (fight until army can no longer produce)
- Add Laser Tower (1x1, hitscan) and Missile Launcher (2x2, guided with min-range dead zone)
  as buildable defensive structures with new towerlaser and towermissile weapons
- Units now hold at weapon range when attacking buildings instead of closing to point-blank,
  controlled by new engageHoldFraction constant (0.45)
- Replace center-to-center distance with surface distance for building targets; buildings are
  treated as rectangles with true half-extents, improving combat accuracy
- Buildings (towers) now freely traverse and aim in all directions regardless of art orientation
- Commander unit flagged with isCommander; victory conditions validate presence of commanders
- Update campaign missions to use destroyCommander objective; reseed m02 (old seed unwinnable
  after combat balance changes)
- Add skirmish setup UI for selecting victory conditions
- Update AI skill ladder verification thresholds to account for engage hold behavior
- Add comprehensive tests for victory conditions and defensive structures
