docs: add RFCs 009-011 (session persistence + ACP support)

Three proposal documents, numbered in dependency order:

- RFC 009: an abstract, append-only, event-based SessionPersistence
  service over the existing SessionEvent log (no parallel persisted
  type), a JSONL impl, a SessionMeta header seam, and an async
  AgentLoop.resume path. Design informed by Codex/Claude Code/
  opencode/pi. Core design point; unblocks resume + ACP session/load.
- RFC 010: ACP (Agent Client Protocol) support as a dsh-acp
  client-driver plugin on @agentclientprotocol/sdk, mapping ACP onto
  the agent/* events and the tools/execute permission seam. Builds on
  009 for session/load; single active session.
- RFC 011: multiplex concurrent ACP sessions over one connection
  (bridge-layer change; downstream of 010).
