feat(directives): drop directives.goal — orchestration reads contract body (#132)

Hard cut. The unified contracts surface owns spec text now; the
directive itself is just a folder. The orchestrator daemon reads the
active contract's body when it spawns, replans, or runs completion.

Schema (migration 20260510000000):
  - DROP TABLE directive_goal_history
  - ALTER TABLE directives DROP COLUMN goal
  - ALTER TABLE directives DROP COLUMN goal_updated_at

New repo helper:
  - get_active_contract_body(directive_id) — picks the
    active|queued|draft contract (in that order), most-recent first.

Backend cuts:
  - Directive / DirectiveSummary / CreateDirectiveRequest /
    UpdateDirectiveRequest lose goal & goalUpdatedAt.
  - CreateDirectiveRequest gains optional `contractBody` — when
    provided, create_directive_for_owner auto-creates a first contract
    with that body in the same transaction.
  - Removed: update_directive_goal, update_directive_goal_keep_orchestrator,
    save_directive_goal_history, get_directive_goal_history,
    DirectiveGoalHistory model, UpdateGoalRequest.
  - Removed handlers::directives::update_goal + the
    /directives/{id}/goal route.
  - orchestration::directive::build_planning_prompt /
    build_completion_prompt / build_order_pickup_prompt now take a
    `contract_body: &str` instead of `goal_history`. classify_goal_change
    + try_interrupt_planner_with_goal_edit + GoalChangeKind +
    GoalEditInterruptResult removed (they were only useful for the
    small-vs-large goal-edit interrupt cycle).

CLI:
  - `makima directive update-goal` removed (UpdateGoalArgs deleted,
    Commands enum trimmed, ApiClient::directive_update_goal +
    UpdateGoalRequest deleted).

Frontend:
  - Directive / DirectiveSummary / CreateDirectiveRequest types lose
    goal & goalUpdatedAt; CreateDirectiveRequest gains `contractBody`.
  - useDirective drops updateGoal helper.
  - api.ts updateDirectiveGoal removed.
  - Legacy DirectiveList + DirectiveDetail components deleted; the
    /directives route now always renders the document-mode page.
    The user-settings documentModeEnabled flag is no longer
    consulted at the route level.
  - NewContractModal passes body via contractBody.
