Fixes #3682
Fix 1: JSON string coercion
LLMs emit array/boolean/number params as JSON-encoded strings. Added _coerce_json_strings() that converts these to native types before call_tool().
Fix 2: gitmcp utility tool discovery
hasattr(server.session, method) always returns True even when transport returns "Method not found". Now checks server_info.capabilities before registering list_resources/list_prompts tools.
