ClimateTraits contained two std::vector<const char *> members for custom fan modes and custom presets. Every get_traits() / traits() call reconstructed these vectors, causing heap allocations on every publish_state() and control()/perform() call — the hottest paths in the climate component. Move the vector storage to the Climate base class and have ClimateTraits hold const pointers instead. get_traits() wires the pointers automatically. This eliminates all heap allocation from ClimateTraits copies, making the struct trivially copyable (floats + bitmasks + 2 pointers). Additionally, set_custom_fan_mode_() and set_custom_preset_() no longer need to call get_traits() just to search for a mode — they search the Climate-owned vectors directly, removing another traits rebuild from the control/perform path.
