refactor(kiro): simplify tool size compression logic

Browse source 
The code refactors the tool building process in initializeAuth to handle
description truncation and size limits more efficiently. It introduces
per-tool description truncation using a fixed max length, and simplifies
the compression logic by removing the iterative description adjustment
loop. This improves code clarity and performance.
