Suppress 'Tool loaded' message for deferred tools

Feature Request

When Claude Code loads a deferred tool via ToolSearch, a "Tool loaded." message is displayed to the user. This is noisy and not useful — the user doesn't need to know about internal tool loading mechanics.

Proposed Solution

Suppress the "Tool loaded." message, or make it configurable to hide.

Use Case

During normal conversation, Claude frequently needs to load tools (Read, Edit, Bash, etc.) and each one produces a "Tool loaded." line that clutters the output.
