Describe the Request

The docs frequently suggest the following pattern:

store = Store('my-store', ...)
register_store(store)

We can change this to an easier one-liner by adding a register flag to Store.

store = Store('my-store', ..., register=True)

In this case, Store can become a singleton type, returning an existing instance if one with a matching name exists and otherwise instantiating a new one and registering it. By default, register=False preserving all prior functionality and skipping the singleton factory.

This opt-in singleton pattern would help prevent users from instantiating the same Store by accident multiple times in the same process, negating the cache/connector persistence benefits.

This might also require some other changes/considerations:

• Add a get_or_create_store() function and move the store lock out of the factory so it can be used in both get_store() and get_or_create_store() (freestanding, in the factory, or in the store singleton factory).

• register is included in the store's config.
• Update docs to suggest register rather than register_store().
