On darwin arm64 the fish-speech editable install (pip install
--no-build-isolation -e) compiles the transitive `tokenizers` Python
package's Rust extension from source, because there is no prebuilt
manylinux wheel for that platform (Linux builds never compile it, so this
only breaks on macOS). The pinned tokenizers crate fish-speech's stack
resolves to contains a `&T` -> `&mut T` cast that the macOS CI runner's
newer Rust toolchain rejects via the now-deny-by-default
`invalid_reference_casting` lint:
error: casting `&T` to `&mut T` is undefined behavior ...
error: could not compile `tokenizers` (lib) due to 1 previous error
ERROR: Failed building wheel for tokenizers
This failed the fish-speech darwin/metal (mps) backend image build in the
v4.5.5 release CI while all Linux variants built fine.
Fix: export RUSTFLAGS with `-A invalid_reference_casting` (appended to any
existing value, not clobbering) before installRequirements so the
unchanged third-party crate compiles as it did under the older toolchain.
Version-agnostic and harmless on Linux, where no Rust compile happens.

The fish-speech metal-darwin-arm64 backend build has been failing on every
release (v4.5.3, v4.5.4, v4.5.5) and is a standing red on the darwin backend
matrix. fish-speech pulls `tokenizers` transitively from its upstream source
(`pip install -e fish-speech-src`), and on darwin/arm64 there is no prebuilt
wheel for the pinned old `tokenizers` version, so pip builds it from source.
Modern rustc rejects that old crate as a hard error:
error: casting `&T` to `&mut T` is undefined behavior ...
--> tokenizers-lib/src/models/bpe/trainer.rs:517:47
= note: `#[deny(invalid_reference_casting)]` on by default
error: could not compile `tokenizers` (lib) due to 1 previous error
This is deterministic, not a flake, and there is no clean fix that does not
either pin a stale Rust toolchain or downgrade a soundness lint guarding real
UB. Until upstream fish-speech moves to a tokenizers version that compiles on
current toolchains, drop darwin support so the release backend build stays
green. The Linux/CUDA/ROCm/Intel/L4T variants are unaffected.
Removes:
- the `-metal-darwin-arm64-fish-speech` entry from `includeDarwin` in
backend-matrix.yml
- the `metal:` capability mappings and the concrete `metal-fish-speech` /
`metal-fish-speech-development` gallery entries in backend/index.yaml
- the now-unused darwin-only requirements-mps.txt

* fix(kokoros): implement new Backend RPCs to fix the build
The backend.proto grew six RPCs (SoundDetection, Depth, TokenClassify,
Score and the bidi-streaming Forward) that the kokoros gRPC service never
implemented, so the trait impl no longer satisfies `Backend`:
error[E0046]: not all trait items implemented, missing:
`sound_detection`, `depth`, `token_classify`, `score`,
`ForwardStream`, `forward`
kokoros is a TTS backend with no use for these, so add `unimplemented`
stubs (plus the `ForwardStream` associated type) matching the existing
pattern for every other unsupported RPC in this file.

* fix(fish-speech): add setuptools-rust for the editable source install
install.sh installs the fish-speech source tree editable with
`--no-build-isolation`, which means the build backends of its transitive
dependencies must already be present in the venv. One of them builds a
Rust extension and its metadata step fails with:
ModuleNotFoundError: No module named 'setuptools_rust'
Add setuptools-rust to requirements.txt so installRequirements provisions
it before the editable install runs.

* fix(llama-cpp-quantization): vendor convert_hf_to_gguf.py with conversion/
Upstream llama.cpp split the model-specific logic out of the single
convert_hf_to_gguf.py file into a sibling `conversion/` package, so the
script now starts with `from conversion import ...`. Downloading just the
one file therefore fails at runtime with:
ModuleNotFoundError: No module named 'conversion'
Clone the repo (reusing the clone already needed to build llama-quantize)
and copy both the script and the `conversion/` package into the backend
dir. Python puts the script's own directory on sys.path[0], so the package
resolves when it sits beside the script.

* fix(sglang): pin the CPU source build to sglang v0.5.11
The CPU profile builds sgl-kernel from a `git clone` of sglang with no
ref, so it always tracks master. Recent master added CPU kernels (e.g.
mamba/fla.cpp) that fail to compile in our builder:
constexpr variable 'scale' must be initialized by a constant
static library kineto_LIBRARY-NOTFOUND not found
Pin the clone to v0.5.11, the same release the GPU path already floors on
(requirements-cublas12-after.txt). Overridable via SGLANG_VERSION so the
pin can be bumped deliberately.
