New internal/adapters/tenantengine package, mirroring
internal/adapters/{lldap,privacyidea,authelia}'s shape: Client.Roles()
calls tenant-engine's cache-read endpoint. Fails open by construction --
unreachable, non-200, malformed body, or a nil *Client all return
(nil, false), never an error to specially handle. Wired into
TokenHandler.TenantEngine (nil by default, existing tests unaffected);
token.go stamps tenant_roles only when ok.
7 adapter tests plus 3 TokenHandler-level tests proving the actual
required behavior end-to-end: present when reachable, token issuance still
200 with every other core claim intact when unreachable (tenant_roles
simply absent -- the literal done-criteria), absent when not configured.
Real bug found and fixed at the source, not worked around: the first live
cross-process check (real flex-auth, real tenant-engine, this adapter)
returned tenant_not_found for a tenant that existed -- tenant-engine's read
endpoint was keyed by its internal tenant_id, but key-cape only ever has
the tenant's profile identifier. Fixed in tenant-engine
(ADHOC-2026-07-24), re-verified with the same live three-process chain --
roles=[IAM] ok=true.
Workplan closed: T01-T03 done. Explicitly still open: client_credentials /
service-token issuance -- no such flow exists in token.go at all, a
materially larger separate piece of work than either task here.

The adapter was forwarding the downstream client's client_id and
redirect_uri to Authelia, which would always be rejected — Authelia
only recognises client_id=keycape and its registered callback URI.
Also removed downstream PKCE forwarding: KeyCape is a confidential
OIDC client to Authelia and authenticates via client_secret instead.
