# 作用：
|
||
# - 将订阅内容转换成 Clash Meta / Mihomo 可用的完整 YAML 配置
|
||
# - 默认使用 subconverter HTTP /sub 接口（最稳）
|
||
# - 失败则跳过，不影响主流程
|
||
#
|
||
# 输入/输出约定：
|
||
# - IN_FILE：原订阅（默认 temp/clash.yaml）
|
||
# - OUT_FILE：转换后的配置（默认 temp/clash_config.yaml）
|
||
#
|
||
# 设计原则：
|
||
# - 绝不 exit 1（失败只 warn 并 exit 0）
|
||
# - 已是完整 Clash 配置则直接 copy
|
||
# - 没有 CLASH_URL（原始订阅 URL）则不转换（subconverter 最稳是 url=...）
