saopig1andClaude Fable 5 846ee30bce fix(qq): pin the QQ Music API sidecar to qqMusicApiPort
The embedded QQ Music API sidecar could bind a different port than the one
the client base URL (getQQMusicBaseUrl) targets. The upstream
@sansenjian/qq-music-api package derives its default port from
process.env.PORT (falling back to 3200) and, in some historical versions,
auto-started that server as an import side effect. When an old build listened
on 3300 while the client requested 3200 (issue #122), fetching the QQ login QR
failed with ECONNREFUSED on 127.0.0.1:3200, so the QR never showed and login /
cookie persistence silently broke.

Align process.env.PORT with the configured qqMusicApiPort for the duration of
the import (restoring the previous value afterwards so nothing else in the
process is affected), reuse an already-listening instance instead of racing a
second listen, and log the port actually bound (read from the socket) so any
mismatch is visible in the logs.

- src/music/api-server.ts: PORT alignment + reuse-on-auto-start + bound-port log
- src/music/api-server.test.ts: regression coverage that the sidecar follows
  qqMusicPort (not an injected PORT) and restores PORT afterwards
- README.md: QQ login FAQ clarifies the sidecar and client share qqMusicApiPort
  and points stale-latest-image users (who saw 3300) at re-pulling the image
