feat(clinic): ADR-251 clinical dashboard + hash-chained RuVector store

Read-only research/clinical instrumentation over the ADR-250 adaptive-gamma
platform, closing two operational gaps: no durable cohort memory, no
clinician surface.

Store (store.rs): append-only JSONL holding anonymized profiles, witnessed
session summaries, and acceptance verdicts. Every line is hash-chained
(entry_hash = SHA-256(prev_hash || raw record bytes)), so any retroactive
edit, deletion, or reorder breaks the chain — the store fails closed (refuses
to open tampered data) and rebuilds the RuVector kNN/clustering layer on open
so cohort warm-start survives restarts. The chain hashes the exact on-disk
bytes via serde_json RawValue, because serde_json's default float parse is
lossy and re-serialization is not byte-stable (this bit the first cut: a
9-session ingest self-corrupted on reopen).

Dashboard (server.rs + embedded dependency-free dashboard.html): Axum surface
with GET routes for participants, per-participant frequency-response map +
session trend with safety-stop markers, cohort clusters, per-program
acceptance verdicts, and a live chain-integrity badge. Strictly read-only — a
test asserts no route accepts POST. Claim discipline inherited: acceptance
payloads carry AcceptanceReport::released_claim (NO_CLAIM on failure), never a
raw program claim.

gamma-clinic binary; ingest_governor bridges the live ADR-250 loop into the
store (pseudonymous, dedup by witness hash). Pseudonymity asserted: the
person_id never reaches disk.

20 tests (13 store/lib + 7 server) + 1 doctest; live binary smoke-tested.
Workspace gate: 2,935 passed / 0 failed.
