[enhancement] sources/flags glob 支持花括号交替 {a,b} #228
Description
现状
glob 不支持 {a,b} 交替;third_party/ffmpeg/libavcodec/{aac,bsf,hevc,opus,vvc}/** 会触发 matched-no-source 警告(这个防呆警告本身很好,准确暴露了问题👍)。
真实用例(ffmpeg-m)
FFmpeg 8.x 的 libavcodec 子目录库(aac/bsf/hevc/opus/vvc)需要同一组 per-glob flags,现状只能写 5 条重复条目:
{ glob = "third_party/ffmpeg/libavcodec/aac/**", cflags = ["-Ithird_party/ffmpeg/libavcodec"] },
{ glob = "third_party/ffmpeg/libavcodec/bsf/**", cflags = ["-Ithird_party/ffmpeg/libavcodec"] },
{ glob = "third_party/ffmpeg/libavcodec/hevc/**", cflags = ["-Ithird_party/ffmpeg/libavcodec"] },
{ glob = "third_party/ffmpeg/libavcodec/opus/**", cflags = ["-Ithird_party/ffmpeg/libavcodec"] },
{ glob = "third_party/ffmpeg/libavcodec/vvc/**", cflags = ["-Ithird_party/ffmpeg/libavcodec"] },期望
glob 语法支持 {a,b}(bash/cargo glob 生态常见);或 flags 条目的 glob 键接受数组 glob = ["...aac/**", "...bsf/**"](解析层更小的改动,零新语法风险)。
