* fix(playback): escape commas in mpv header fields on the TS paths PR #1321 fixed the comma truncation of --http-header-fields inside the native embedded-mpv addon, but the same OPT_STRINGLIST parsing bites three TypeScript call sites that join header fields with ',': - external MPV CLI launch (--http-header-fields=...) - external MPV instance reuse (set_property http-header-fields) - embedded MPV frame-copy loadfile options (opt.http-header-fields); the helper's %len% quoting protects only the option-list level, mpv still stringlist-parses the value afterwards The Stalker MAG user agent contains "(KHTML, like Gecko)", so strict portals received a truncated X-User-Agent and rejected live streams with HTTP 400 (#910). Escape backslashes and commas per field with the same scheme as the native fix, via a shared util. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * test(playback): cover the reused-instance IPC header escaping Review follow-up (Greptile on #1323): the regression coverage only exercised the CLI spawn path. Capture the JSON IPC traffic of a second, reused mpv launch and assert the escaped MAG user agent survives the set_property http-header-fields transport, so later serialization changes cannot silently reintroduce truncated headers. net is mocked with a passthrough default because the VLC specs bind a real ephemeral port via createServer.

/**
|
|
* mpv's `http-header-fields` option is a comma-separated list
|
|
* (OPT_STRINGLIST). Header values that themselves contain commas — e.g. the
|
|
* Stalker MAG250 user agent "...(KHTML, like Gecko) MAG250" — must be escaped
|
|
* or mpv splits them into bogus fields and the server rejects the request
|
|
* (HTTP 400). mpv strips the backslash and keeps the comma inside the value.
|
|
* Mirrors the escaping of the native embedded-mpv addon (PR #1321).
