fix(homecore-api security): auth-gate GET /api/ (was unauthenticated) + recover WS subscription on broadcast lag (#1076)
* fix(homecore-api security): auth-gate GET /api/ (HC-API-AUTH-01, ADR-161)

`rest::api_root` took no headers and unconditionally returned
`200 {"message":"API running."}`, while every sibling REST route gates
on `BearerAuth::from_headers`. HA's `APIStatusView` inherits
`requires_auth = True`, so `/api/` must return 401 for a missing/wrong
bearer — HA clients use it as a token-validation probe, so a 200 told a
bad-token client its token was valid and let an unauthenticated party
confirm a live endpoint. LOW severity (static body, no data leak),
reported at true severity.

Fix: `api_root(headers, State)` validates the bearer like `get_config`.

Pinned by fails-on-old tests (200 -> assert 401):
- api_root_rejects_missing_bearer
- api_root_rejects_wrong_bearer
guarded by api_root_accepts_correct_bearer (still 200 with valid token).

* fix(homecore-api security): recover WS subscription on broadcast lag (HC-WS-LAG-01, ADR-161)

`subscribe_events`'s per-subscription task matched `Err(_) => break` on
both broadcast `recv()` arms. `RecvError::Lagged(n)` (a slow consumer
falling >EVENT_CHANNEL_CAPACITY=4,096 events behind) is recoverable —
the bus doc says "Lagged receivers must re-sync" and HA keeps the
subscription alive across a lag. The old code treated the first lag as
fatal, so after an event burst the client's stream went permanently
silent with no error frame — a self-inflicted event-delivery DoS under
load. LOW severity.

Fix: `Lagged(_) => continue` (skip dropped window, re-sync),
`Closed => break`, on both the system and domain arms.

Pinned by subscription_survives_broadcast_lag: subscribes, floods 6,000
filtered events past the 4,096 capacity to force a Lagged, then asserts
a subsequent subscribed event is still delivered (old code: 5s timeout).

* docs(homecore-api security): record HC-API-AUTH-01 + HC-WS-LAG-01 review (ADR-161)

CHANGELOG [Unreleased] Security entry + ADR-161 addendum documenting the
beyond-SOTA network-API review: two LOW bugs fixed (unauthenticated
GET /api/; WS subscription killed on broadcast lag) and the
auth/traversal/injection/info-leak/CORS dimensions confirmed clean with
evidence (no traversal surface — in-memory DashMap + EntityId allowlist;
HashSet token compare, not a byte-== timing oracle).

ruv e7b1b66f74 docs(adr): ADR-162 — plugin security + bounded RunModes; mark ADR-161 P4/P5/§A5 DONE
ADR-162 records the M8 work that makes ADR-161's honestly-deferred plugin
security claims TRUE: P4 (Ed25519 signature + SHA-256 integrity verification,
secure-default trust policy), P5 (capability/authority isolation on
hc_state_set), and §A5 (bounded Restart/Queued/max RunModes). Each fix MEASURED
with a failing-on-old test; threat model table (tampered module, untrusted
publisher, over-privileged write, run-mode exhaustion); cog-ha-matter Ed25519
reuse cited; remaining honest deferral (key provisioning/rotation, native
in-process plugins, HAP pairing).

ADR-161 deferred-backlog lines for P4/P5/RunModes struck through and marked
DONE → ADR-162; §B5 note points forward to the now-implemented P4 gate.

ruv d0da5888e3 docs(adr): ADR-161 — HOMECORE server-layer security & honest-labeling sweep (M7)
Records the Milestone 7 audit: library cores are real (anti-slop positive) but
the network boundary had a CRITICAL WS auth bypass (A1) + reply-theater (A2) +
documented-but-no-op automation (A3-A7) + a network-exposed dev bin (A8), all
fixed and graded MEASURED with failing-on-old tests. Cites the NO-ACTION
security positives (uuid::v4 CSPRNG refuted-suspicion, hardened CORS,
no-traversal migrate, no-secrets-in-logs, honest HAP stub) and the deferred
backlog (plugin authority-isolation P5, sig-verification P4, HAP real pairing
P2, bounded run-modes, YAML load-at-boot).
