Both methods reject top-level entity params with "Use filters: { userId:
"..." } instead", and docs/open-source/node-quickstart.mdx teaches that same
shape. But search() and getAll() only read filters.user_id / .agent_id /
.run_id, so following either one throws a second, contradictory error:
"filters must contain at least one of: user_id, agent_id, run_id".
Normalize the three camelCase aliases to snake_case before validation in both
methods, so the shape the SDK tells callers to use actually works. An explicit
snake_case value wins if both are supplied, and the camelCase key is dropped
rather than passed through to the vector store as a stray metadata field.
