Instead of runtime null, duplicate, and capacity checks in register_component_, make the method unreachable from outside codegen by removing the public template wrapper and granting friend access to the codegen-generated ::setup() function. Since ESPHOME_COMPONENT_COUNT is set to exactly len(CORE.component_ids) at codegen time, the StaticVector is always correctly sized and the runtime capacity check cannot trigger from codegen. External components that bypassed codegen to call App.register_component() directly will now get a compile error, forcing them to properly declare their components in their config schema.
