glm-5.2 87b2c2a5ef docs(arch): hub-wiring cluster — aggregated env, peer_operations, from_call cleanup, alknet-hub crate spec

Three ADRs addressing gaps surfaced by the first hub consumer (alkapi):

- ADR-067: Aggregated peer-env wiring — Dispatcher::with_aggregated_env hook
  so compose_root_env reads a shared PeerCompositeEnv across all calls,
  not a fresh per-call one. The hub-defining gap (alkapi OQ-08 / G.1).

- ADR-068: PeerCompositeEnv::peer_operations override — adds
  list_operation_names() to OperationEnv, overrides on OverlayOperationEnv
  and PeerCompositeEnv. Fixes services/list-peers returning empty operation
  lists for non-local peers (alkapi G.6).

- ADR-069: from_call is a manual free function, not auto-wired — reverses
  the aspirational OQ-27 resolution to match the implementation. Cleans
  the 'v1 default' hedging language in ADR-017 and client-and-adapters.md
  (alkapi G.4).

New crate spec: alknet-hub — reusable hub pattern (aggregated env,
connection lifecycle, worker supervision with backoff, service discovery).

Spec fixes: builder API drift (with_local/with_local_streaming separation),
ScopedOperationEnv → ScopedPeerEnv type name, OQ count 51→54.

Three new OQs: OQ-52 (wait_for_close), OQ-53 (backoff defaults),
OQ-54 (inbound hook placement).

OQ-27: from_call Re-Import Trigger

Origin: client-and-adapters.md, ADR-017 Assumption 4
Status: resolved (2026-07-09 — amended from 2026-06-27 resolution)
Door type: Two-way
Priority: low
Resolution: from_call is a manual free function; the assembly layer calls it after connect(). The overlay is per-connection (Layer 2, ADR-024), so a stale overlay dies with the connection; re-import on reconnect is naturally scoped to the new connection. A CallConnection::refresh() method for mid-connection re-discovery is a genuine feature addition — non-breaking, additive — if a deployment needs manual re-discovery without drop-and-reconnect. See ADR-069 for the full rationale.

The original 2026-06-27 resolution ("auto-re-import on connection establishment") was aspirational — written before the implementation existed. The implementation made the right call (manual free function); this amendment aligns the spec with the implementation.
