feat(memory): add lightweight read modes for scalability

[surapuramakhil]

Add optional parameters to read_graph, search_nodes, and open_nodes tools to address context explosion in long-running deployments:

• read_graph: metadataOnly, includeObservations, observationLimit, entityTypes
• search_nodes: limit, includeObservations, observationLimit
• open_nodes: includeObservations, observationLimit, observationOffset (pagination)

Fixes #3953
