RSPEED-2658: Remove dead GraniteToolParser and legacy Agents API imports

[major]

Description

The GraniteToolParser class was a workaround for llama-stack-client-python#206, built for the old Agents API. The codebase has migrated to the Responses API and this class has zero production callers. This removes it, its legacy imports from llama_stack_client.lib.agents (AgentCompletionMessage, AgentToolCall), and the corresponding unit tests.

Cool, code deletion, not slop addition ;)
