Mirror the 11 whisper golang Dockerfile matrix entries (CPU amd64/arm64,
CUDA 12/13, L4T CUDA 13, Intel SYCL f32/f16, Vulkan amd64/arm64, L4T
arm64, ROCm hipblas) with backend and tag-suffix substituted to crispasr.

Add the crispasr meta anchor and its full set of image gallery entries
(cpu, metal, cuda12/13, rocm, intel-sycl f32/f16, vulkan, L4T arm64,
L4T cuda13 arm64, plus -development variants), mirroring the whisper
backend gallery block.

* build(crispasr): don't wire fixture-gated test into test-extra

Mirror the whisper Go backend: its AudioTranscription test is gated on
model/audio fixtures and skips in CI, so building crispasr (the heaviest
ggml compile in the tree) inside the unit-test lane adds a long compile
for zero coverage. The backend image build in backend-matrix.yml remains
the authoritative compile check.

* ci(crispasr): add darwin metal build entry (mirror whisper)

The metal-crispasr gallery entries and capabilities.metal mapping
reference -metal-darwin-arm64-crispasr, which is only produced by an
includeDarwin entry. Mirror whisper's darwin metal entry so the tag
actually gets built.

* feat(crispasr): switch shim to crispasr_session_* multi-architecture API

The shim used whisper_full(), which in CrispASR is the whisper-only path:
libcrispasr only transcribes Whisper GGUFs through it. Multi-architecture
transcription (Parakeet, Voxtral, Qwen3-ASR, Canary, Granite, FunASR,
Paraformer, SenseVoice, ...) goes through the crispasr_session_* C-ABI,
which auto-detects the architecture from the GGUF and dispatches to the
matching backend.

Rewrite the C shim around crispasr_session_open / _transcribe_lang /
_result_* and add get_backend() so the selected backend is logged.
load_model now takes a threads param (session_open binds n_threads at
open). The session result is segment+word based with no token IDs and no
per-decode callback, so drop n_tokens / get_token_id /
get_segment_speaker_turn_next / set_new_segment_callback. set_abort is
kept for API parity but is best-effort: the session transcribe is blocking
with no abort hook.

Update the purego bindings and gocrispasr.go to match: tokens are left
empty, speaker-turn handling is removed, and AudioTranscriptionStream
emits one delta per non-empty segment after the blocking decode returns
(no progressive streaming via the session API), preserving the
concat(deltas) == final.Text invariant.

crispasr_session_set_translate is exported by libcrispasr but not declared
in crispasr.h, so it is forward-declared in the shim alongside the
open/transcribe/result functions.

* build(crispasr): link full CrispASR backend set for multi-arch support

The shim's crispasr_session_* dispatch calls into the per-architecture
backend libs (parakeet, voxtral, qwen3_asr, canary, funasr, paraformer,
sensevoice, ...), which CrispASR builds as static archives. Linking only
crispasr + ggml dead-stripped every backend object from the final module
(nm backend-symbol count: 0), leaving a whisper-only .so.

Link the same backend set as crispasr-cli so the static archives are
pulled in. After this the module carries the backend symbols (nm count
407, .so grows from ~2.1MB to ~6.7MB) and the session API can dispatch to
every compiled-in architecture.

Also rewrite ${CMAKE_SOURCE_DIR}/examples/talk-llama to
${PROJECT_SOURCE_DIR}/... in the vendored src/CMakeLists.txt: CrispASR
locates its vendored llama.cpp via ${CMAKE_SOURCE_DIR}, which is wrong when
CrispASR is add_subdirectory'd (CMAKE_SOURCE_DIR points at this backend
dir, not the CrispASR root). PROJECT_SOURCE_DIR is correct both standalone
and as a subproject; the sed is idempotent.

* test(crispasr): adapt suite to session API (blocking, no decode callback)

Register the new symbol set (drop the removed token/speaker/callback funcs,
add get_backend; load_model now takes 2 args). The session transcribe is
blocking with no abort hook, so a mid-decode cancel can't interrupt it:
change the cancellation spec to cancel the context before the call and
assert codes.Canceled from the pre-call ctx.Err() check, dropping the
<5s mid-decode timing assertion. The streaming spec still holds with
per-segment post-decode emission (>=2 deltas, concat(deltas) == final.Text).

* feat(gallery): add CrispASR ASR model entries (-crispasr)

Signed-off-by: Ettore Di Giacinto <mudler@localai.io>

* fix(gallery): keep only session-auto-detectable CrispASR ASR models

The crispasr backend loads models via crispasr_session_open, which
auto-detects the backend from the GGUF general.architecture using
crispasr_detect_backend_from_gguf. Architectures not in that detect
map cannot be opened, so those gallery entries fail to load.

Removed entries whose architecture is not wired into CrispASR
v0.6.11's session auto-detect router (they can be re-added when
upstream maps them):

- Not in the detect map: data2vec, firered-asr, funasr,
  fun-asr-mlt-nano, glm-asr, hubert, kyutai-stt, mega-asr, mimo-asr,
  moonshine{,-de,-streaming,-tiny-de}, omniasr{,-llm,-llm-1b},
  paraformer, sensevoice.
- Pending verification (filename-heuristic routed, not arch-detected):
  parakeet-ctc-0.6b, parakeet-ctc-1.1b. Their GGUFs are routed to the
  fastconformer-ctc backend by a filename heuristic in the model
  registry, which implies general.architecture is not a mapped string.

Kept the parakeet rnnt/tdt_ctc variants: convert-parakeet-to-gguf.py
writes general.architecture="parakeet" unconditionally and encodes the
rnnt/ctc distinction in metadata fields, so they session-auto-detect.

* feat(crispasr): TTS synthesis via crispasr_session_synthesize (24kHz)

Add tts_synthesize/tts_free/tts_set_voice to the C-ABI shim. They reuse
the already-open g_session (crispasr_session_open auto-detects a TTS
model) and dispatch to the upstream synthesis call, which returns
malloc'd 24 kHz mono float PCM. Orpheus needs a SNAC codec path that we
do not set, so it returns NULL here and surfaces as an error Go-side.

* feat(crispasr): implement TTS/TTSStream gRPC methods

Bind the new shim functions via purego and implement TTS, TTSStream and
a writeWAV24k helper. synthesize copies the C-owned PCM out before
freeing it; TTS writes a 24 kHz mono 16-bit WAV to req.Dst via
go-audio/wav. CrispASR has no progressive synth, so TTSStream
synthesizes fully, encodes to WAV, and emits the bytes as a single
chunk; it owns the results-channel close (the gRPC server wrapper ranges
until close), mirroring vibevoice-cpp's TTSStream.

* feat(gallery): add CrispASR vibevoice-tts model entry

Only vibevoice-tts works through the current shim: qwen3-tts, chatterbox,
and orpheus require companion codec/s3gen/SNAC paths (set_codec_path /
set_s3gen_path) that the shim doesn't wire yet, and kokoro/indextts/voxcpm2
aren't in the session auto-detect map. Those are follow-ups.

* fix(crispasr): satisfy golangci-lint (errcheck defers + unsafeptr nolint)

The crispasr Go file is entirely new, so new-from-merge-base lints every
line (unlike the grandfathered whisper backend it was forked from):
- handle os.RemoveAll / fh.Close return values in AudioTranscription
- annotate the two intentional C-pointer unsafe.Slice sites with //nolint:govet

* feat(crispasr): backend: and codec: model options (explicit arch + companion files)

Add two model-config options to the CrispASR backend via opts.Options:

- backend:<name> selects an explicit CrispASR backend (bypassing
  auto-detect) by routing load_model through
  crispasr_session_open_explicit, unlocking architectures the
  detector won't pick on its own (qwen3, cohere, granite, voxtral,
  moonshine, mimo-asr, orpheus, kokoro, chatterbox, etc.).
- codec:<path> loads a companion file (qwen3-tts codec, orpheus SNAC,
  chatterbox s3gen, or mimo-asr tokenizer) via the universal
  crispasr_session_set_codec_path setter after the session opens. A
  relative path resolves against the model directory. rc==0 means
  success or not-applicable; only a negative rc is fatal.

The C shim load_model gains a backend_name argument and a new
set_codec_path entry point; the Go bridge parses the prefix:value
options and registers the new symbol. The vad_only path is unchanged.

* refactor(gallery): use virtual.yaml base for crispasr models

The crispasr entries are just backend + model + a couple options, fully
expressed inline via overrides:/files: in gallery/index.yaml. Point each
url: at the shared gallery/virtual.yaml (the established 'virtual' model
trick) and drop the 36 redundant per-model gallery/*-crispasr.yaml files.

* fix(gallery): drop voice-requiring TTS entries (keep vibevoice-tts)

Real e2e showed qwen3-tts/orpheus/chatterbox don't synthesize through the
current shim: the codec: companion loads fine, but these engines additionally
need a voice pack / voice prompt / reference clip (qwen3-tts base errors
'no voice'; chatterbox is zero-shot cloning; orpheus uses named voices) that
the backend doesn't wire. (qwen3-tts also can't auto-detect: its GGUF arch is
'qwen3tts', unmapped by the detector — would need backend:qwen3-tts.) Removed
to avoid shipping non-working gallery entries; vibevoice-tts (built-in voice,
e2e-verified) remains the working TTS. Voice-pack wiring is a follow-up.

* feat(crispasr): speaker: and voice: TTS options (baked speakers + voice packs/prompts)

speaker:<name> -> crispasr_session_set_speaker_name (baked speakers: qwen3-tts
CustomVoice, orpheus). voice:<path>(+voice_text:<ref>) -> crispasr_session_set_voice
(voice-pack GGUF, or WAV zero-shot clone with ref text). Applied at Load as the
default voice; req.Voice still overrides the speaker per request.
