rtx-csm: AudioSeal apply CLI for arbitrary-rate WAVs

End-to-end watermarker driver that handles any source sample rate by
resampling to AudioSeal's 16 kHz native, embedding, then resampling back.
Tested on 10s of real CSM 24 kHz speech: mean_presence=0.9988 detection,
12/16 message bits round-trip (4-bit erosion from double resample).

- examples/audioseal_apply.rs: --in/--out/--source-rate/--message; loads
  source via audio_io::load_mono_at_rate, calls AudioSealWatermarker
  through the public Watermarker trait, verifies via in-process detect.
- Fix bit-match counter overflow in audioseal_demo.rs and audioseal_apply.rs.

rtx-csm: AudioSeal watermark — Rust port end-to-end

SEANet generator + detector matching `facebook/audioseal` reference layout
(weight_norm-merged via pure-Rust pickle reader). Verified on real CSM
speech: mean_presence=0.9943, 16/16 message bits decoded.

- src/audioseal.rs: SeanetEncoder (4-stage strided downsample, 2-layer
  LSTM bottleneck at 512 channels, 128-dim projection), MsgProcessor
  (16-bit message via embedding sum + broadcast-add), SeanetDecoder,
  Generator (encoder+msg+decoder), Detector (encoder + single 320×
  reverse_convolution + 1×1 head). Padding mirrors audiocraft
  _get_extra_padding_for_conv1d exactly.
- src/audioseal_convert.rs: candle_core::pickle reads .pth directly;
  merge_weight_norm computes g*v/‖v‖ over all axes except 0; writes
  flat safetensors keyed identically to what Generator/Detector read.
- examples/audioseal_inspect.rs: dumps tensor keys + shapes.
- examples/audioseal_convert.rs: HF download + convert CLI.
- examples/audioseal_demo.rs: load + embed + detect on real WAV or
  synthetic burst, optionally writes watermarked WAV.
- audio_io.rs gains generic load_mono_at_rate, resample, write_wav_mono
  (16 kHz path needed for AudioSeal).

12 new unit tests + 2 converter tests; 63 lib tests total green.
