missile_config.lua

-- Missile launcher configuration. Shared by the Missile Command Center widget
-- (launch/build behaviour) and integral_menu_config.lua (Launch tab layout), so a
-- missile type is described in exactly one place. One entry per launch button, in
-- display order. Command ids are assigned automatically from CMD_BASE below.
--
-- Entry fields:
--   key       - internal id (widget command table key).
--   unit      - unit def name; supplies the button icon.
--   label     - display name.
--   col, row  - position in the Launch tab grid.
--   tooltip   - button tooltip.
--   cmdType   - "ICON_MAP" (default) or "ICON_UNIT_OR_MAP" (can target a unit).
--   siloBuild - unit this type is built as at a missile silo (enables Alt-click build).
--   zenith    - true for the Zenith meteor controller (special, non-stockpile behaviour).
--   controllerScope - "separate": this button only exists when Eos/Scylla are NOT combined.
--   launch    - list of launchable unit types, each:
--       unit      - unit def name that carries/fires this missile.
--       cmd       - "ATTACK" or "MANUALFIRE".
--       weaponId  - weapon index on that unit.
--       stockpile - "silo" (sits on a silo pad) or "engine" (GetUnitStockpile); omit for Zenith.
--       scope     - "combine": active only when Eos and Scylla are combined.
