docs: re-key architecture docs off the alknet mono-repo — speak as alkcall

The ported docs still framed alknet siblings (alknet-core/-call/-channels/
-http/-tls/-client) as live load-bearing context of this crate. With the
extraction complete and alknet headed for glue-level replacement, the docs
now speak as alkcall and cite the real sibling crates (alkhttp, alktls,
alktty, alktunnels, alktrader).

- ADR-054 (new): re-own the verifier-selection rule in-crate — three
  remote roles (public X.509 endpoint / transport relay / hub),
  ServerCertVerifier by PeerEntry presence, RemoteIdentity None
  load-bearing. Provenance: alknet ADR-034 (never ported), demoted to
  footnote. Resolves OQ-21's cross-repo authority gap.
- OQ-43 (new, deferred(scope)): composition-layer ownership and shape
  after the alknet replacement — the named receiver for the
  downstream-side deferrals (OQ-33 endpoint layer, OQ-41 QUIC-native
  substrate, OQ-42 hub broker, OQ-19 persistence adapters, ADR-045 dial
  seam). README layering diagram redrawn with the composition layer as
  TBD-ownership instead of "alknet / alknode" in concrete.
- Spec docs reframed: titles, self-references, dial/TLS/from_jsonschema
  homes, malformed legacy cite rows removed; dead relative research
  paths qualified as source-repo paths.
- ADR amendments (append-only): 027 (alknet-http -> alkhttp), 031 (post-
  extraction state), 044 (split landed as modules in alkcall), 045
  (name normalization; citation-space note).
- Citation hygiene: unprefixed/colliding source-repo cites prefixed
  ("alknet ADR-NNN (provenance)") across 009/011/022/034/035/038/040/
  043/044/045; stale OQ cites corrected (session registries OQ-04, batch
  semantics OQ-03, verifier rule ADR-054); stale anchors fixed.
- README provenance note consolidated; citation conventions documented.

Verification: markdown link check (all local links resolve, all in-crate
ADR cites point at existing decisions/ files); table integrity check
(uniform row widths across open-questions.md and edited tables); residual
alknet-mention sweep (only provenance/historical/intentional framing
remains); architecture review subagent pass with zero remaining criticals.
Docs-only change — no code paths touched.

+This ADR's decision text was authored when the HTTP host crate was
+named `alknet-http` inside the alknet mono-repo. The HTTP host is now
+the standalone sibling crate **`alkhttp`**, which wraps alkcall
+(extraction context: ADR-031; the adapter-location rule is unchanged —
+the trait lives in alkcall, HTTP-backed adapters live in `alkhttp`).
+The title's "in alknet-http" and the body's crate-name references
+should be read as "in `alkhttp`"; the References below link to the
+source-repo originals (provenance). The `FromJsonSchema` provenance
+variant remains in alkcall.
