feat(memory2): durable saved locations anchored in map across restarts

Problem

tag_location("kitchen") works, but after a cold boot from a different pose, navigate_with_text("kitchen") cannot resolve the same physical place. The failure is also silent and the default behaviour drive to the wrong coordinates.

Solution

• Introduce a new persistent location system (LocationStore / LocationMemory) that lets the robot save locations with accurate map references, allows updates, and clearly reports errors if a location can't be used.
• Connect relocalization status and map identity (RelocStatus, map_id) so the system knows whether a location is based on up-to-date mapping data or stale information.
• Update navigation skills to use the new location system automatically when available, clearly telling the agent which locations are temporary (session-only) and which are saved permanently; navigation will automatically retry if the robot's position changes due to relocalization.
• New unitree-go2-agentic-locations blueprint, which combines agentic features, relocalization, and the new saved location memory.

How to Test

unit test with uv run pytest dimos/memory2/test_locations.py dimos/memory2/test_location_module.py \ dimos/agents/skills/test_navigation.py -k "navigate_to_location or location" -q
