ADR-091: ConnectionCredentials — decouple the dial credential bundle
from the call protocol. CallCredentials (call-protocol-level, carries
auth_token) was being used as the dial's credential type, coupling the
dial to the call protocol. The auth_token is a hub-layer identity
correlation mechanism (browsers, alknet/register), not a transport
credential. ConnectionCredentials (transport-level: local_identity +
remote_identity) is the dial's credential bundle; all three dial
signatures unify on &ConnectionCredentials; dial_iroh's node_id
parameter is derived from remote_identity.fingerprint. CallCredentials
stays in alknet-call with auth_token. The shape is validated by the
future dial_ssh pattern (russh's check_server_key + authenticate_publickey
consume the same two dimensions).
Amends ADR-089 §3 (dial signatures) and §5 (move consequence), ADR-087
(input framing). Updates client/tls/call/core crate specs and the
extraction plan's Phase 0/3/4/5.
Migration plan cleanups (findings.md):
- Remove duplicated ordering-rationale bullets (copy-paste artifact)
- TL;DR: six phases -> seven (Phase 0 promoted); four compilable
intermediate states -> each phase leaves workspace compilable
- Remove inline 'Wait — that's 10, not 8' self-correction; fix
Category B header to (10 tests)
- Replace contradictory line ranges in Net Phase 5 test impact with
name-based references
- Decide quinn feature fate: removed (not no-op)
- Note webpki-roots always-present per ADR-088 §5 in Phase 1 dep list
