Glenn Thompson 9d5166c562 feat: Add Harmony backend with dummy drain for streaming pipeline 
- harmony-backend.lisp: Audio pipeline connecting Harmony to encoders
- Uses :dummy drain to capture PCM without audio output
- Reads from packer bip-buffer via request-read/finish-read API
- Encodes PCM to MP3 via LAME and feeds to stream server

All three systems compile cleanly:
  cl-streamer, cl-streamer/encoder, cl-streamer/harmony

Glenn Thompson 6c15441a08 feat: Add MP3 and AAC encoder FFI bindings 
- LAME FFI (lame-ffi.lisp) for MP3 encoding
- FDK-AAC FFI (fdkaac-ffi.lisp) for AAC encoding
- High-level encoder wrappers (encoder.lisp, aac-encoder.lisp)
- Fix compilation warnings in buffer.lisp and icy-protocol.lisp

Both encoders tested and loading successfully:
- LAME version: 3.101
- FDK-AAC: libfdk-aac.so.2

Next steps: Harmony integration for audio pipeline

Glenn Thompson e1be88a54a feat: Initial cl-streamer skeleton for CL-native streaming 
- Architecture document outlining Icecast/Liquidsoap replacement
- Core streaming server with ICY metadata protocol support
- Thread-safe ring buffer for audio data
- Mount point abstraction with metadata updates
- Multi-client connection handling

This is experimental groundwork for integrating with Harmony/cl-mixed
and playlisp/parsector for a pure CL streaming solution.
