Description

Fixes #3795

Adds the metadata parameter to the public update() method in both Memory and AsyncMemory classes. The internal _update_memory() function already supported metadata updates, but this parameter was not exposed to the client-facing API. This change allows users to update memory metadata when updating memory content.

Type of change

• Bug fix (non-breaking change which fixes an issue)

How Has This Been Tested?

Automated Tests

6 new unit tests were added covering both sync and async update paths:

tests/test_main.py (sync Memory):

• test_update — verifies None metadata is passed by default when not specified
• test_update_with_metadata — verifies a metadata dict ({"category": "sports", "priority": "high"}) is forwarded to _update_memory
• test_update_with_empty_metadata — verifies empty {} is passed through (not coerced to None)

tests/memory/test_main.py (async AsyncMemory):

• test_async_update_without_metadata — same as sync, confirms None default
• test_async_update_with_metadata — same as sync, confirms metadata forwarding
• test_async_update_with_empty_metadata — same as sync, confirms empty dict passthrough

All 6 tests verify that the metadata argument is correctly forwarded from the public update() API to the internal _update_memory() method.
