Reconcile the canonical model and discovery with the runtime
Closes gap G02 of the scope assessment for the client-registration and discovery
surface. spec/canonical-model.yaml and domain/model.go both claimed to be the
source of truth and disagreed: the spec restricted grants to authorization_code,
required redirect URIs of every client, and omitted the audience, service
subject, tenant, role, MFA and handoff fields the runtime reads.

The durable part is the link, not the edit. A two-way conformance test compares
the spec against the Go model by reflection and fails when a runtime field has
no spec entry or a spec entry is not read by the runtime, the latter unless
marked runtime: false. It found drift beyond the assessment's list on its first
run -- User.tenant was undeclared -- which is the argument for the check over a
one-time reconciliation.

Discovery now advertises the core profile claims that appear on every token and
derives scopes_supported from the registered clients rather than a fixed list.

The Go model is stated as the runtime authority and the YAML as the reviewed
contract, in both files. This covers client registration and discovery, not
schema enforcement in general, which remains G06.

description: >
Canonical Identity Model for KeyCape / NetKingdom IAM Profile.
This file is the reviewed contract for identity entities. The runtime
authority is src/internal/domain/model.go: the server reads Go structs, not
this YAML. The two are held together by an executable conformance check
(src/internal/domain/conformance_test.go, KEY-WP-0017), which fails the build
when a runtime field has no entry here or an entry here is not read by the
runtime.
So: change the Go model and this file together. A field declared here but
deliberately not implemented must carry `runtime: false`, which is how the
check tells a reserved field apart from a forgotten one.
