Spawned background agents can now be given a relayed summary of the project owner's recent 'timeline' posts

What

New code assembles what the project owner recently wrote on "its timeline" and passes it into the context given to a spawned background agent when it starts, with a preface explaining that this is context only, not an instruction to follow. A killswitch can anonymize the attribution so it shows as "unattributed" instead of naming the owner.

Why

This gives background agents visibility into recent owner activity as background context, while the disclaimer guards against the agent mistaking that context for a command, and the killswitch offers a way to strip owner identity from it if needed.
