Implements oceanic fleet blockade mechanics with warship catalog, sea chokepoints, harpoon grappling, broadside cannons, and toll enforcement for the MMORPG. Harpoon range gating was fixed to use specific harpoonRangeTiles instead of control radius. No issues found.

✅ Bug: Harpoon range ignored; uses control radius instead

fireHarpoonGrapple determines whether a target is reachable via isVesselInBlockadeZone, which compares distance against blockade.controlRadiusTiles. The per-warship harpoonRangeTiles value (25/35/45) defined in WARSHIP_CATALOG and WarshipData is never read anywhere, so the advertised harpoon-range mechanic is non-functional — all warships grapple at the control radius regardless of class. Compute the harpoon distance separately and gate the grapple on WARSHIP_CATALOG[blockade.warshipClass].harpoonRangeTiles.
