feat(overwrite): set provider format by extension

Add an overwrite that infers and sets rule-provider 'format' from URL or path extensions. Implements .mrs -> mrs and .yaml/.yml -> yaml, ignores query/fragment and case, prefers URL first for remote providers and path first for file-type providers, and leaves other formats unchanged. Implemented via a ruby_edit script in overwrite/Rule_Provider_Format_Fix.conf.

+# - 远程 rule-provider 优先根据 url 后缀判断，再回退检查 path
+# - type: file 优先根据 path 后缀判断，再回退检查 url
+# - .mrs 设为 format: mrs
+# - .yaml/.yml 设为 format: yaml
+# - URL 查询参数和片段不影响判断，扩展名不区分大小写
+# - 其他格式保持不变
