Discord enforces DAVE (E2E encryption) on all voice channels. py-cord currently decodes Opus packets before stripping the DAVE application-layer encryption, causing OpusError: corrupted stream and making voice reception completely non-functional. Changes: - reader.py: Rewrite decrypt_rtp() to call dave.decrypt() BEFORE Opus decoding. Handles SSRC-to-user_id race condition by trying all known DAVE user IDs when the mapping is not yet populated, then caching the result. Falls back to OPUS_SILENCE on decrypt failure. - opus.py: Remove erroneous dave.decrypt() call in _decode_packet() that was applied to already-decoded PCM data, corrupting the audio stream. - router.py: Catch OpusError and AssertionError in _do_run() gracefully, emitting a single warning instead of crashing the router thread. Fixes: #3139
