refactor(tool)!: rename date-picker type to date-range - #377

Summary

• rename DATE_PICKER to DATE_RANGE
• change the tool parameter wire value from date-picker to date-range
• preserve the existing { start, end } prompt schema

Why

This parameter represents a date range value, not a UI picker. date-range pairs directly with the existing date type and keeps presentation terminology out of the protocol.

Breaking change

This intentionally removes DATE_PICKER and date-picker without compatibility aliases. SDK v0.10.1 included the previous name, so consumers using it must update Python enum references and plugin YAML manifests.
