Follow-up to #55 / #57 / #58.

What was missing

#55 added Earshot to the backends table, the dependency snippet, and the feature-flag table — but not to the part of the README where each backend is actually explained. WebRTC, Silero, TEN-VAD and FireRedVAD each have a ### section with a description and a runnable example; Earshot went straight from the FireRedVAD example to the trait docs. Someone who enabled the feature had nowhere to look for how to construct it.

The new section follows the same shape as the other four and calls out the three things that differ from them:

• construction is infallible, so there is no .unwrap() on new()
• the frame size is exactly 256 samples, with a pointer to FrameAdapter for 20 ms / 320-sample transports
• each detector holds ~8 KiB of streaming state, so one per stream, and reset() between streams

FrameAdapter::process_each

The adapter rework in #55 added process_each and made the allocation behaviour of each method meaningful, but the README still listed only the three older methods. Added it to the example, with a note on which methods allocate and what buffered_samples() reports — this is the method to reach for on a real-time path, and it was invisible.

Acknowledgements

Added the earshot crate (MIT OR Apache-2.0, by pyke — the same authors as ort, already credited).

Notes

• Both new code examples were compiled and run against the crate. The README is not wired into doctests, so CI would not have caught a mistake in them.
• I did not repeat upstream's accuracy claim. Their README states Earshot is more accurate than Silero VAD v6 and TEN VAD; on the TEN-VAD testset this crate benchmarks against, our measurement puts it at F1 0.928 — level with TEN-VAD and below Silero's 0.938, with the speed advantage intact. The benchmark table speaks for itself, so the section sticks to characteristics rather than comparisons.
• The benchmark table itself is untouched. It is generated by the update-benchmarks job and chore: release v0.1.17 #56 already has the regenerated five-row version, so hand-editing it here would only conflict.
