Mem0 Support for filters in V2 Search API

[giles17]

Motivation and Context

This PR updates the Mem0Provider to support dynamic, per-invocation filters that align with the mem0 v2 API design. The change enables flexible memory filtering at query time while maintaining backward compatibility.

In _provider.py:

• Updated invoking() method to accept filters via **kwargs and pass to mem0 search API
• Added _build_filters() method to build filter dictionaries from:
  • Init parameters (user_id, agent_id, thread_id, application_id) as base scope
  • Optional per-invocation filters passed through kwargs
  • Invocation filters take precedence for overrides
• Changed search API call from individual parameters to unified filters dict

In mem0_basic.py:

• Added 12-second delay for memory processing

Pull request overview

This PR adds support for the Mem0 search v2 API's filter parameter, transitioning from passing individual filter parameters (user_id, agent_id, run_id) to a unified filters dictionary. This enables more advanced filtering capabilities including logical operators, date ranges, and complex queries.

Key Changes:

• Modified the invoking() method to accept an optional filters kwarg and use a centralized _build_filters() method
• Updated all tests to verify the new filters dictionary format instead of individual parameters
• Added a 12-second delay in the sample to accommodate Mem0's asynchronous memory processing

File	Description
python/packages/mem0/agent_framework_mem0/_provider.py	Implemented _build_filters() method to consolidate init parameters into a filters dict and merge with optional invocation filters; updated invoking() to pass filters dict to mem0 search API
python/packages/mem0/tests/test_mem0_context_provider.py	Updated existing tests to verify filters dict format; added comprehensive test coverage for _build_filters() method with various scenarios including merging, overriding, and exclusion of None values
python/samples/getting_started/context_providers/mem0/mem0_basic.py	Added 12-second sleep between memory storage and retrieval to handle Mem0's asynchronous processing

Would it be possible to add an example how it looks like from user perspective?
