feat: implement Ace doctrine — core packages, API routes, DB migration, Meridian screens

[Copilot]

Establishes the canonical Ace architecture: intent → policy → recommendation → approval → execution → live recovery. Lays the full structural foundation across packages, API, DB, and mobile surfaces.

New packages (packages/)

• ace-core — canonical TS types: Principal, Operator, TripIntent, TravelPolicy, ApprovalDecision, JourneySession
• ace-policy — pure policy evaluators: canOperatorAct, getApprovalRequirement, canAutoBook, evaluateOperatorSpendLimit; implements the approval ladder (auto → human_confirm → escalate)
• ace-delegation — operator registry: createOperatorRecord, isOperatorActive, revokeOperator, typed AllowedAction enum
• ace-events — 15 event type literals with payload shapes + AceEmitter interface + makeAceEvent factory
• ace-runtime — BookingAdapter, PaymentAdapter interfaces + ExecutionRequest/Result, RerouteAction, RollbackAction contracts

DB migration 036 (additive only)

Six new tables: ace_principals, ace_operators, ace_travel_policies, ace_trip_intents, ace_approvals, ace_journey_sessions — all IF NOT EXISTS, all indexed.

API routes at /ace/ (apps/api-edge/src/routes/ace/)

Full intent lifecycle mounted at /ace:

POST   /ace/principals                  → create principal + default policy
GET    /ace/principals/:id/policy       → read travel constitution
PATCH  /ace/principals/:id/policy       → update travel constitution

POST   /ace/operators                   → register delegated operator
DELETE /ace/operators/:id               → revoke

POST   /ace/intents                     → submit intent (human or agent)
POST   /ace/intents/:id/plan            → run policy evaluation → recommendation + approval gate
POST   /ace/intents/:id/approve         → human or agent decision
POST   /ace/intents/:id/execute         → create JourneySession, begin booking
GET    /ace/journeys/:id                → live journey state (polling; SSE in subsequent phase)

Meridian screens (apps/meridian/app/(main)/)

• converse/ — monolithic converse.tsx (3494 lines) replaced by a directory: index.tsx preserves all existing behaviour; _voice-runtime.tsx (mic state machine hook), _session-orchestrator.tsx (turn history + journey continuity), _recommendation-surface.tsx (plan card + approval badge)
• approval/[intentId].tsx — three visual states: policy_auto / human_confirm / escalate
• delegation/index.tsx + delegation/[operatorId].tsx — trusted operator list + per-operator trust config with revoke
• policy/index.tsx — travel constitution UI: rail auto-book limit, flight confirmation toggle, class preference, max arrival hour, operator permissions link
• journey/_disruption-card.tsx + journey/_recovery-surface.tsx — live disruption display + reroute options; escalation/support surface
