* fix(audio): add streaming resampler
* fix(audio): preserve stream resampling state
* fix(audio): keep playback callback nonblocking
* fix(audio): decouple capture conversion from dasp
* fix(audio): support stateful samplerate backend
* refactor(audio): isolate stream callback state
* refactor(audio): group capture output options
* fix(audio): clear stale playback state after startup failure
Reset non-Linux playback state when stream startup fails to prevent
new-format audio from using the previous stream or resampler.
Add regression tests for failed format changes and successful playback.

* fix(audio): honor capture resampler selection and reuse buffers
Use the selected resampling backend for fixed-frame capture.
Convert samples directly into the input queue and
reuse the PCM frame buffer.
Add tests for anti-aliasing, thread transfer, and
partial-frame draining.

* fix(audio): reset incompatible Linux playback state on
startup failure
Preserve compatible output streams when replacement
startup fails.
Clear state when no compatible stream exists and cover
both paths in tests.

* perf(audio): reuse PCM buffers in the capture pipeline
- Reuse capture framing, resampling, and channel conversion buffers
- Deliver borrowed packets and write Sinc output into reusable storage
- Add allocation and output-equivalence regression tests

* fix(audio): smooth buffer discard discontinuities
Signal receiver PCM discards and fade from the current playback output when the callback reaches the new timeline.

* perf(audio): move capture encoding off the CPAL callback
Move Opus encoding and service delivery to a dedicated worker.
Use a preallocated bounded PCM queue with explicit loss reporting.
Add tests for callback allocations and queue saturation.

queued audio duration alongside capture loss statistics.

* fix(audio): avoid blocking capture on encoder queue contention
Use preallocated queues with try_lock in the capture callback.
Count and drop the current packet on contention, preserving
drop-oldest behavior on overflow.
Add regressions for paused workers, buffer reuse, and sequence wrap.

* fix(audio): avoid waiting on playback callback locks
Use one PCM try_lock attempt and preserve queued samples during contention. Replace readiness locking with per-stream atomic status and report callback errors from the receiving thread.
Cover callback progress, retained audio, recovery, and poisoned-buffer handling.
* fix(audio): restart capture after processing errors
Stop further processing until the service recreates the stream.
Document the guard as defensive recovery for an unconfirmed failure.
Group capture and resampler submodules under their parent directories.

- Document packet rejection on contention even when buffers are available
- Extend existing contention and saturation test assertions
