review: symmetric policy-service type imports, drop stale inprocess peers, pin child-switch and fork-default cases

- child-agent.ts declares both policy-service augmentations as explicit
  empty type imports, so removing the ApprovalPolicy import cannot
  silently degrade ctx.get('approval') typing.
- dsh-subagent-inprocess no longer consumes the policy services in src,
  so its optional peers and tsconfig references are dropped; both
  policy-inheritance Agent Notes state the current ownership.
- The continuable suite pins that a later child-side switch beats the
  delegation snapshot and that an unswitched fork parent seeds no
  policy events.

## Consequences
- Default-bundle background delegation (`backgroundMode: continuable`) now inherits a parent's explicit sandbox and approval overrides; compositions without either policy service behave unchanged.
- `dsh-subagent` gains optional peer types on `dsh-sandbox-policy` and `dsh-user-approval` (the `ctx.get` pattern the one-shot driver used); `dsh-subagent-inprocess` keeps its optional peers but delegates to the shared helpers.
- `dsh-subagent` gains optional peer types on `dsh-sandbox-policy` and `dsh-user-approval` (the `ctx.get` pattern the one-shot driver used); `dsh-subagent-inprocess` drops its policy-service peers and type imports entirely and delegates to the shared helpers.
- The continuable suite (`packages/subagent/subagent/tests/continuation-inheritance.spec.ts`) pins fresh-start seeding, pre-await capture, default omission, cold-resume snapshot stability, and fork-seed precedence; the ACP snapshot scenario `subagent-continuable-inheritance` pins the child's delegation event and read-only runtime context through the assembled app and fails when the capture is removed.
- Out-of-process providers (`acp`, `dsh-sdk`, `claude-code`, `codex`) support no continuable children (`prepareContinuable` absent), and their one-shot children keep their own deployment policy (`inheritsParentContext = false`); cross-process policy propagation remains out of scope.
