feat: auto-gate radiators on heat network surplus

Radiators and Thermal Canister Missile launchers pull from the same heat
pool with identical NetworkResourceOutput settings, and priorities.rules
defines no ordering for heat. A constantly-running radiator therefore
spends missile ammunition to make steam.

Gate radiator dissipation on three network signals instead of the raw
PowerToggle: a 98%/94% hysteresis band on the thermal battery, whether
any launcher is actually set to thermal ammo, and an override driven by
the engine's own OverflowHeatStorage as a safety net.

Storage fullness causes no damage on its own -- only overflow does, and
only above 350 status per tile -- so the band sits high deliberately to
keep the network full as a missile reserve.

Signal polarity is "hold", not "vent", so any ship missing a broadcaster
falls back to vanilla behaviour.

Includes an offline validation suite that resolves every patch target,
component reference and component Type against the installed game data,
since all three otherwise fail only as a crash on game load.

+# ABOUT ME
+# Installs the Auto Radiator mod into Cosmoteer's user Mods folder.
+#
+# Why it exists: Cosmoteer loads mods from the user profile directory, which on
+# a Proton install lives deep inside the Steam compatdata prefix and is awkward
+# to find by hand. This script locates it, validates the mod against the
+# installed game data first, and copies only the files the game needs.
+#
+# Usage:  ./install.sh            install (validates first)
+#         ./install.sh --uninstall  remove the installed copy
