Remove Apex Dynamics faction, retune bullet speed/size

Drop Apex Dynamics from the playable roster (2 races now: Inner Sphere
Navy, Outer Rim Collective) to simplify the 2D art pipeline; World's
race-offer logic just shuffles both remaining races instead of picking
2 of N. Also fix bullets using a constant muzzle velocity instead of
adding the shooter's own velocity, and shrink the bullet hitbox/sprite.

-### Apex Dynamics — The Corporate Syndicate
-**Weapon type:** High-tech energy (coherent light / plasma)
-**Visual:** Sleek, pearlescent-white hulls with razor-sharp geometric lines and

-### The Rock-Paper-Scissors Loop
+### Faction Interaction
+
+With only 2 factions, the abilities form a single counter rather than a loop:
 
-- **ORC mines counter Apex cloak** — a cloaked ship blundering through a mined
-  corridor eats the blast, which also breaks the cloak.
 - **ISN shield counters ORC mines** — the frontal barrier absorbs a mine
   detonation, clearing the path for the team behind it.
-- **Apex cloak counters ISN shield** — a slow, frontal-shielded push leaves the
-  ISN ship's flank and engines open for a cloaked ship to slip around and
-  punish.
+- **ORC mines punish a shield push once it drops** — the shield can't fire and
+  loses turn rate while up, so a mine dropped in its path (or behind it, once
+  the barrier expires) still threatens the push.
 
 No ability wins a fight by itself — it depends on the map and the moment it's
 used, same as a smoke/flash/molotov in CS:GO.
