Refactor: all plugin subdirectories use option patterncopilot/modify-plugin-files-subdirectories

Apply the same functional options pattern from plugin/singbox to:
- plugin/mihomo (mrs_in.go, mrs_out.go)
- plugin/plaintext (text_in.go, common_in.go, common_out.go, text_out.go, clash_in.go, clash_out.go, json_in.go, surge_in.go, surge_out.go)
- plugin/maxmind (all input/output files)
- plugin/v2ray (dat_in.go, dat_out.go)
- plugin/special (cutter.go, lookup.go, private.go, stdin.go, stdout.go)
- lookup.go and merge.go updated to use new constructors
