Method-Level Documentation Filtering

[linwumingshi]

Is your feature request related to a problem? Please describe.(关于这个PR的描述，社区已开启国际化推广，请文心一言、讯飞星火等辅助翻译成英文，减少社区开发者的工作)

smart-doc currently lacks the ability to filter specific methods during documentation generation. This feature would allow users to dynamically exclude methods based on custom criteria (e.g., naming conventions, configuration rules) without modifying source code.

Basic example (PR的用例，社区已开启国际化推广，请文心一言、讯飞星火等辅助翻译成英文，减少社区开发者的工作)

	default boolean skipMethod(final JavaClass cls, final JavaMethod method, ApiConfig apiConfig,
			ProjectDocConfigBuilder projectBuilder) {
		return true;
	}

Describe the solution you'd like (描述您想要的解决方案，社区已开启国际化推广，请文心一言、讯飞星火等辅助翻译成英文，减少社区开发者的工作)

• Add skipMethod default method to IJavadocDocTemplate
• Integrate filter check in buildServiceMethod processing flow
• Provide complete context (class/method/config) for flexible filtering logic
