feat: check command -@param/@returns tag validation

[Zih0]

Changes

• Validate JSDoc completeness for exports with @public tag
• Detect missing @param and @returns tags
• Detect unused @param tags that don't match actual parameters
• Extract validatePublic function for testability

Each declaration type has its own validator with specific validation targets:

Declaration	Validator	Validates
function	FunctionValidator	params, returns
interface	InterfaceValidator	properties, methods
...

TODO

Currently, the build command treats params, properties and members as @param
I think each of them should be handled separately
