Introduce the Desktop safety foundation for the relay-canonical managed-agent
migration. State + classification only — no migration enablement, no
destructive local mutation. Every existing record defaults to LegacyOnly, so an
upgrade that predates any migration deserializes unchanged and keeps local JSON
+ keyring authoritative.
- Add `managed_agents::authority` with a single internally-tagged
`RelayAuthority` enum (`LegacyOnly` | `RelayAuthoritative { evidence }`), so
impossible states are unrepresentable: authoritative structurally carries a
verified head, legacy structurally cannot. No `{"state":{"state":...}}`
nesting — persisted shape is `{"authority":"legacy_only"}` /
`{"authority":"relay_authoritative","evidence":{...}}`, asserted exactly.
- Add `#[serde(default)] relay_authority: RelayAuthority` to
`ManagedAgentRecord`; a store predating the field deserializes as LegacyOnly.
- Add an exhaustive field→codec-home classification table
(`FIELD_CLASSIFICATIONS`) as a single source of truth, verified against the
ACTUAL PersonaEventContent (30175) / ManagedAgentEventContent (30177)
builders and the 30177 exclusion asserts — not intent:
* start_on_app_launch, auto_restart_on_config_change, provider_binary_path,
persona_team_dir carry through NO codec slot -> TransientLocal.
* avatar_url IS carried by 30175 -> stays DefinitionProjected.
- Tighten the exhaustiveness test to exact set equality: every record field has
a class AND every class key still names a live field (no stale drift).
- Populate `relay_authority` explicitly (`RelayAuthority::legacy()`) at every
production/test constructor rather than relying on a struct-wide default.
Foundation-only classification/authority API is consumed by the not-yet-landed
reconcile/migration lanes; suppression is per-item with a named consumer, not
module-wide.
