fix(subagent): preserve caller-owned local child discovery

Caller delivery previously suppressed both settlement messages and local catalog membership. Workflows therefore stopped publishing the durable parent-child edge that the parent header and recursive discovery require. The workflow panel only opens running members, and the ordinary sidebar hides subagent Sessions, so completed workflow transcripts had no normal navigation path even though their logs still existed. Record every successfully admitted local child in its parent's catalog, independently of the result recipient. Membership answers which local Sessions belong to the parent; delivery answers who consumes this activation's result. Keeping those decisions separate restores completed-child and descendant discovery without duplicating workflow completion messages or adding return guidance to caller-owned work. Publication failures retain the existing rollback transaction for both delivery modes. These local children intentionally retain the unified continuable mode: list_agents includes them, the parent catalog opens their transcripts after reload, and the existing direct-parent controls can cold-resume them. No one-shot execution path or additional lifecycle state is introduced. Caller-owned external executions still use their consumer's membership records because they have no local Session to open. Update the existing bilingual service/workflow documentation and decision records, refresh the owning workflow/Ralph/advanced Session recordings and Python SDK event expectations, and preserve unrelated recorded stream times. Validation: - Full repository build passed. - 443 subagent, workflow-host, and Ralph tests; 14 list_agents tests passed. - Four focused headless workflow/advanced snapshot refreshes and replays passed. - Three shipped-Web workflow tests passed, including completed-child catalog navigation after reload and the continuable composer. - Python SDK advanced and scheduler-recovery snapshots refreshed and replayed through the built dsh CLI with Python 3.12. - Three discovery regressions fail with the original catalog exclusion and pass after restoring this fix. - test:docs (20 gates), doc-sync (42 gates), lint:contracts-ready, Host and Client TypeScript builds, and git diff --check passed.

 The shared activation entry point, external execution ownership, and caller-versus-parent result delivery are governed by [Unified subagent activations](../simplification/2026-09-17-unified-subagent-activations.md). This record retains the independent rationale described below.

-The parent Session's required `subagent/catalog` events are the persistent authority for direct-child discovery. Only parent-delivery children enter the catalog; caller-owned executions retain their caller's membership records. Each event contains `childId`, `childCreatedAt`, mode, and the mode-discriminated label. Local children use `continuable`; external executions use `external` and cannot be opened as local Sessions. Historical `one-shot` and `unknown` entries remain readable. Invalid own facts, including unsupported payload versions, reject projection restoration because silently dropping a required fact would return an incomplete catalog.
+The parent Session's required `subagent/catalog` events are the persistent authority for direct-child discovery. Every local child enters the catalog independently of its result recipient; external children enter only with parent delivery. Workflow membership records describe execution progress and do not replace local Session discovery. Each event contains `childId`, `childCreatedAt`, mode, and the mode-discriminated label. Local children use `continuable`; external executions use `external` and cannot be opened as local Sessions. Historical `one-shot` and `unknown` entries remain readable. Invalid own facts, including unsupported payload versions, reject projection restoration because silently dropping a required fact would return an incomplete catalog.

 Creation publishes only successful facts. A local activation admits the initial prompt before appending its catalog event. An external activation appends its event after provider startup and before returning the receipt. Failed admission or publication releases the unpublished execution; there is no compensating catalog event or rollback protocol.

Both local and external activations deliver their result after handle cleanup, capacity release, and settlement notifications.
