fix(thinking-block-validator): handle text content parts in message validation

Previously, the validator only checked for tool_use parts, causing 'Expected thinking but found text' errors when messages had text content. Renamed hasToolParts to hasContentParts to include both tool_use and text types.

Also added CommentCheckerConfigSchema support for custom prompt configuration.
