fix(docker): bump rust 1.85 -> 1.90 + enforce LF on shell scripts

Two real bugs found while pushing the v0.8.0 image to Docker Hub:

## Rust 1.85 -> 1.90

`hnsw_rs 0.3.4` (transitive via wifi-densepose-ruvector ->
ruvector-attn-mincut -> hnsw_rs) calls `nbp.is_multiple_of(500_000)`.
`is_multiple_of` on unsigned integers was stabilised in Rust 1.87
(rust-lang/rust#128101 — RFC 3565). On 1.85 the compile fails with:

  error[E0658]: use of unstable library feature `unsigned_is_multiple_of`
   --> hnsw_rs-0.3.4/src/hnswio.rs:736:20

Pinned to 1.90 for reproducibility — a comment in the Dockerfile flags
the 1.87 MSRV requirement so a future downgrade can't quietly break it.

## .gitattributes — force LF on shell scripts + Dockerfile

Without a `.gitattributes`, git's default `core.autocrlf=true` on
Windows converts shell scripts to CRLF on checkout. `COPY`ing
`docker/docker-entrypoint.sh` into a Linux image then preserves CRLF.
The shebang line `#!/bin/sh\r\n` causes `exec /app/docker-entrypoint.sh`
to fail with:

  exec /app/docker-entrypoint.sh: no such file or directory

The kernel tries to look up an interpreter literally named `/bin/sh\r`,
which doesn't exist. Container exits immediately. The first v0.8.0
image push (digest sha256:7957…44fa) suffered exactly this; the
re-pushed image (digest sha256:e9f4…d38315) was built on a
renormalised tree.

The .gitattributes rule forces LF for:
  - *.sh / *.bash
  - Dockerfile*
  - docker/* (covers docker-entrypoint.sh + docker-compose.yml)
  - scripts/*
  - `verify` (the proof-replay wrapper — same root cause as if it
    had landed CRLF in someone's clone)

Binary file globs (*.bin, *.wasm, *.rvf, *.pcap, etc.) explicitly
marked binary so text-normalisation never touches them.

## CHANGELOG — drop the false `--introspection` flag claim

The CHANGELOG entry for v0.8.0 said the introspection endpoints were
"off by default, enabled via `--introspection`". That isn't true:
`sensing-server --help` has no such flag. The routes are mounted
unconditionally in `main.rs`. The per-frame `update()` p99 of
0.041 ms (~24× under D4's 1 ms budget) makes always-on viable; the
"off by default" framing came from an earlier draft of ADR-099 that
the implementation outgrew. Corrected.

## Verification

End-to-end smoke test of the pushed image:

  docker run -d -p 13000:3000 -e CSI_SOURCE=simulated     -e SENSING_BIND_ADDR=0.0.0.0 ruvnet/wifi-densepose:v0.8.0

  /health -> {"status":"ok","source":"simulated",...}
  /api/v1/info -> {"backend":"rust","features":{"ruvector":true,"signal_processing":true,...}}
  /api/v1/introspection/snapshot -> {"regime":"unknown",
    "regime_changed":false,"top_k_similarity":[]} (ADR-099 shape exact)
  /ui/observatory.html -> HTTP 200, 15 KB

Published manifest digests:
  ruvnet/wifi-densepose:v0.8.0 -> sha256:e9f4c5af…d38315
  ruvnet/wifi-densepose:latest -> sha256:e9f4c5af…d38315

+# Reference platforms for `expected_features.sha256`
+
+The hash in `expected_features.sha256` was generated on a specific BLAS / FFT
+backend. Numpy + scipy delegate FFT/linear-algebra to platform-native
+libraries, and those libraries produce **bit-different output on identical
+IEEE 754 inputs** depending on the backend. This is not a bug in the proof
+pipeline — it is a property of the underlying numerical libraries. (See
+issue #560.)
+
+## Platforms where the hash is expected to MATCH
+
+| Platform | BLAS backend | Status |
+|---|---|---|
+| `linux-x86_64-gnu` (Python 3.11.x, numpy 1.26.4 from PyPI wheels, scipy 1.14.1) | OpenBLAS | ✅ Reference |
+| `windows-x86_64-msvc` (Python 3.11.x / 3.13.x, numpy 1.26.4 from PyPI wheels, scipy 1.14.1) | OpenBLAS | ✅ Reference |
+
+## Platforms where the hash is **expected to MISMATCH**
+
+| Platform | BLAS backend | Why |
+|---|---|---|
+| `darwin-arm64` (macOS arm64, Apple Silicon) | Accelerate.framework | FFT + matrix kernels differ in last-bit positions; the SHA-256 will differ even with pinned `numpy 1.26.4` / `scipy 1.14.1`. |
+| Any environment with MKL installed | Intel MKL | Same root cause as Accelerate: different vectorized FFT path. |
+
+## What to do if you get MISMATCH on a non-reference platform
+
+The pipeline is still correct on your platform — the *output* is bit-different
+because the *backend* is bit-different, not because the proof code has a bug.
+Three workable responses:
+
+1. **Run the proof on a reference platform** (Linux x86_64 or Windows x86_64
+   with the PyPI OpenBLAS wheels). This is what CI does.
+
+2. **Generate a new local-reference hash** for your platform and check it
+   against the same hash on a teammate's machine with the *same* backend:
+
+   ```bash
+   # Regenerate from your platform
+   python archive/v1/data/proof/verify.py --generate-hash
+
+   # Commit the new hash to a side file (do NOT overwrite expected_features.sha256
+   # unless you are publishing a new cross-platform reference)
+   ```
+
+3. **Compare numerical output, not the hash.** A relaxed-tolerance comparison
+   on the feature vectors (e.g. `np.allclose(features, reference, atol=1e-10)`)
+   will pass across backends. This is on the roadmap (see issue #560).
+
+## The `verify.py` runtime environment block
+
+Every run of `verify.py` now prints a `RUNTIME ENVIRONMENT` block before the
+pipeline runs. Include that block in any issue report — it identifies the
+platform + numpy version + BLAS backend in one place.
