Claude 281a7d967e fix: harden stream socket transport and protocol from PR review ...

Address several stream socket review findings on the transport, its
consumer client and the wire protocol:

- ParseAllowedUids rejects negative, out-of-range and non-round-tripping
  uids instead of wrapping or truncating them (e.g. 2^32 no longer
  becomes uid 0).
- StreamSocketClient backs off after a connection the producer closes
  before any message, so a rejected consumer (uid allow-list, client
  limit) no longer busy-loops; a rejection is not reported as a
  disconnect.
- SendMedia drops packets for a stream that has no announced HELLO, and
  ClearAudioParams forgets a previously announced audio stream (bumping
  the generation and re-issuing the surviving video HELLO), so a stale
  audio HELLO is never replayed and media never precedes its HELLO.
- Header pts_us is encoded as signed (two's-complement) microseconds so
  negative and AV_NOPTS_VALUE timestamps survive the wire; the dump tool
  decodes it as signed and tracks sequence gaps per generation so a
  generation reset is not mistaken for packet loss.

Tests cover the uid rejections, the audio HELLO clearing and media
guard, the connection-rejection backoff, and signed pts round-trips.
