Module topic 

Topic pattern matching for event routing.

Supports wildcard patterns for flexible event subscription:

• * matches a single segment (e.g., "user.*" matches "user.created" but not "user.foo.bar")
• ** matches multiple segments (e.g., "user.**" matches "user.created" and "user.foo.bar")
• Exact match when no wildcards are present
