Add comprehensive unit tests for the ToolRegistry covering registration, lookup, execution, context injection, async callbacks, schema generation, provider definition conversion, and concurrent access. Fix a defensive edge case in Truncate where a negative maxLen would cause a slice bounds panic, and add table-driven tests covering boundary conditions, zero/negative lengths, and Unicode handling.
