+/**
+ * Create and register a Pinia store implemented with the setup API (core factory).
+ *
+ * Builds the reactive store instance, wires its state into the global Pinia state tree,
+ * wraps actions for $onAction tracking, attaches $patch/$reset/$subscribe/$dispose helpers,
+ * applies plugins and devtools metadata, and registers the store on the provided Pinia
+ * instance. Also prepares Hot Module Replacement (HMR) support and optional hydration logic.
+ *
+ * @param $id - Unique store id used as the key in pinia.state and for registration.
+ * @param setup - Store setup function that receives setup helpers and returns state, getters, and actions.
+ * @param options - Optional store definition/options; used for plugins, getters (options API compatibility), and hydration.
+ * @param pinia - The Pinia root instance where the store will be registered.
+ * @param hot - When true, build the store in hot-update mode (uses a temporary hotState and enables HMR-specific wiring).
+ * @param isOptionsStore - Set to true for stores created from the Options API so certain setup-store behaviors (like state wiring) are skipped.
+ * @returns The reactive Store instance exposing state, getters, actions and Pinia helpers.
