Fusion Agent 0b4dbd219b FN-125: prevent workflow agents from creating tasks ...

Stop workflow executor agents from creating ordinary tasks while preserving explicit self-spawned dependency handling.

- Gate task creation by session identity and execution context.
- Add self-spawned dependency support, validation, and persistence coverage.
- Update agent prompts, tools, documentation, and CLI integration.
- Add a published-package changeset.
