💥 Unify SimplePlugin interceptors into single parameter

[tconley1428]

Summary

• 💥 BREAKING CHANGE: Replace separate client_interceptors and worker_interceptors parameters with a single unified interceptors parameter in SimplePlugin
• Automatically separate client and worker interceptors based on type implementation
• Ensure exactly one instance of each interceptor per worker to prevent duplication

Breaking Changes

For SimplePlugin Users

Before:

plugin = SimplePlugin(
    "MyPlugin",
    client_interceptors=[my_client_interceptor],
    worker_interceptors=[my_worker_interceptor]
)

After:

plugin = SimplePlugin(
    "MyPlugin",
    interceptors=[my_client_interceptor, my_worker_interceptor]  # Mixed list
)

The plugin will automatically:

• Apply client interceptors to clients
• Apply worker interceptors to workers and replayers
• Prevent duplicate invocation when the same interceptor implements both interfaces

Implementation Details

• Updated configure_client() to filter unified interceptors to client-only types
• Updated configure_worker() to filter unified interceptors to worker types and prevent duplication with client-registered interceptors
• Updated configure_replayer() to use worker interceptors from unified list
• Fixed OpenTelemetryPlugin and OpenAIAgentsPlugin to use new parameter
• Added comprehensive type casting to handle union types properly

Test Coverage

• All existing plugin tests pass with updated parameter usage
• Comprehensive test coverage for interceptor duplication prevention
• Tests verify exactly one invocation per worker for combined client/worker interceptors
