Loïc Wisniewski b50597b757 Garrison laser vessels and gas bombers, on a shared ability seam
#105 shipped with interceptors as the only garrisonable vessel, and the
reason was a design fault rather than a decision: firing the laser and the
gas bomb lived in the player's fleet controllers, so a stationed laser would
have held its position and never shot.

The shot is now a thing in the world rather than something a controller
draws. LaserBeamEffect and GasBombEffect are self-contained, self-animating
and self-freeing, added to the tree root - the same shape EnemyBigLaserBeam
and ArtilleryShell already had on the enemy side - and they outlive the
vessel that fired them.

Above them sits one seam, on VesselCooldownFillComponent: ability_range(),
ability_ammo_resource(), ability_ammo_cost() and fire_ability(). A beam and a
bomb are now the same shape of thing to whoever pulls the trigger, so the
garrison AI never names an ability - the test asserts that literally, by
reading the AI's own source. A third armed vessel needs to implement the
seam and nothing else.

Ammunition is the CALLER's business, deliberately: the fleet spends from its
hold, a garrison from its outpost's store, and neither concern belongs in
the component. A garrison with an empty magazine holds fire rather than
falling back on the fleet's hold.

Outpost storage: 50 gas per stationed bomber and 50 energy per stationed
laser, off the VESSEL definitions, so an outpost never learns which vessel
needs what. It is a capacity, not a stock - hub transporters fill it exactly
as they fill a gas burner's buffer, because building_logistics_deficit now
takes the larger of the definition's static buffer and the garrison's
magazine. Every other resource is capped at zero: an outpost is not a depot,
and ore parked at one has nothing to do there and no transporter coming for
it.

Also restores two properties the Godot editor dropped from
GasBurnerBuildingDefinition.tres when it re-saved the file:
collected_outputs and capabilities. Without the first, nothing ever collects
the burner's energy - test_gas_burner caught it.
