refactor: consolidate toolset validation into ToolsetGroup
- Add Default field to ToolsetMetadata and derive defaults from metadata - Move toolset validation into WithToolsets (trims whitespace, dedupes, tracks unrecognized) - Add UnrecognizedToolsets() method for warning about typos - Add DefaultToolsetIDs() method to derive defaults from metadata - Remove redundant functions: CleanToolsets, GetValidToolsetIDs, AvailableToolsets, GetDefaultToolsetIDs - Update DynamicTools to take ToolsetGroup for schema enum generation - Add stubTranslator for cases needing ToolsetGroup without translations This eliminates hardcoded toolset lists - everything is now derived from the actual registered tools and their metadata.
