docs(adr): ADR-100 + ADR-101 — record v0.0.1 shipping status (#644) 

Updates both ADRs to reflect that the first cog (`cog-pose-estimation@0.0.1`)
landed today via PRs #642 + #643.

ADR-100 (Cog Packaging Specification):
* Status line: "first conforming cog shipped 2026-05-19".
* Migration step 2 marked complete with PR references and the GCS
  paths the binaries live at.

ADR-101 (Pose Estimation Cog):
* Status line: "v0.0.1 shipped 2026-05-19".
* New "v0.0.1 shipping status" section that walks through every
  ADR-100 acceptance gate with concrete pass/fail evidence (binary
  sizes, sha256 round-trip, signature, manifest path, live install
  on cognitum-v0, runtime contract, real-weights load assertion,
  ONNX parity).
* Measured-metrics table: training time (2.1 s/400 epochs on RTX 5080),
  PCK@20/PCK@50/MPJPE, cold-start latency for Windows/ruvultra/Pi 5.
* Carries forward the two open follow-ups: Hailo HEF (SDK-gated) and
  PCK@20 >= 35% (data-bound, #640).
* "See also" link to docs/benchmarks/pose-estimation-cog.md.

2. ✅ Land ADR-101 (`cog-pose-estimation` — first Cog built to this spec). Shipped in PR #642 + #643 on 2026-05-19; signed `arm` and `x86_64` binaries live at `gs://cognitum-apps/cogs/{arm,x86_64}/`; install verified on cognitum-v0.
3. After two clean releases of `cog-pose-estimation`, re-publish the existing cogs (`anomaly-detect`, `presence`, etc.) with `binary_sha256` + `binary_signature`. Track in a follow-up issue.
4. Flip `cognitum-cog-gateway` from "verify when present" to "require signature" — separate ADR, separate review.

## v0.0.1 shipping status — 2026-05-19
PRs `#642` (scaffold + arm release + ONNX + live install) and `#643` (x86_64 release) landed on `main`. Acceptance gates from ADR-100 met as follows:
| Gate | Status |
|------|--------|
| Cog binary exists per arch | ✅ arm (`3,741,976 B`) + x86_64 (`4,548,856 B`) on GCS |
| Manifest matches schema | ✅ `cog/artifacts/manifests/{arm,x86_64}/manifest.json` |
| Binary sha256 + Ed25519 signature | ✅ both signed with `COGNITUM_OWNER_SIGNING_KEY`, round-trip verified |
| Public-readable GCS | ✅ anonymous HTTP GET works, SHA matches |
| Live install on a real appliance | ✅ `/var/lib/cognitum/apps/pose-estimation/` on `cognitum-v0` (Pi 5), same layout as `anomaly-detect` |
| Runtime contract (`version \| manifest \| health \| run`) | ✅ all four return correct output; `run` emits `pose.frame` events |
| Real weights loaded (not stub) | ✅ `cargo test` asserts `backend.starts_with("candle-")` + non-zero confidence |
| ONNX artifact (for downstream HEF) | ✅ `pose_v1.onnx` (12 KB), parity vs torch = 8.94e-8 |
| Metric | Value |
|--------|-------|
| Training time (RTX 5080 / Candle CUDA) | 2.1 s for 400 epochs |
| PCK@20 / PCK@50 / MPJPE (1,077-sample seated-desk session) | 3.0% / 18.5% / 0.093 |
| Cold-start: Windows x86_64 | 76 ms |
| Cold-start: ruvultra x86_64 | **5.4 ms** |
| Cold-start: Pi 5 aarch64 | **8.4 ms** |
| Tests | 5/5 pass |
Open follow-ups carried forward from this ADR's "Acceptance gates" section:
- **Hailo HEF cross-compile** — `pose_v1.onnx` is ready; still gated on Hailo Dataflow Compiler + self-hosted runner provisioning. Tracked separately.
- **PCK@20 ≥ 35%** — explicitly not an acceptance gate of this ADR, but the limiting factor on practical usefulness. Tracked in [#640](https://github.com/ruvnet/RuView/issues/640): needs ~30× more paired samples + multi-room camera framing. Today's seated-desk session is the demonstrated bottleneck.
