Support an optional user ID everywhere

[abrookins]

A multi-user environment requires supporting user IDs for every operation. It should be optional, so the server continues to work for single-user environments.

NOTE: Significant AI slop in this one, still tweaking it.

• [nitpick] Consider adding a clarifying comment on the key parts ordering (i.e. namespace, user_id, session_id) to help maintainers understand the rationale behind this structure.

• Ensure that the use of 'dist' instead of 'distance' is consistently applied across the codebase and documented appropriately, so consumers of this API are aware of the change.
