Tianyi Cui 9a4006cb2b feat(agent): create/resume factory seam
Add the agent-creation factory seam on ctx.agents (AgentRegistry):
setFactory/create/resume plus the AgentFactory interface and
CreateAgentOptions/ResumeAgentOptions. AgentLoop implements AgentFactory
and registers itself via ctx.agents.setFactory(this), so plugins
create/resume agents through the interface without depending on the
concrete loop package.

- create({ agentId, sessionId, meta?, agentOptions? }) — programmatic
  create on a caller-supplied session id (e.g. an ACP-generated id).
- resume({ agentId, resumeSessionId, agentOptions? }) — load a persisted
  session via ctx.sessionPersistence (RFC 009) and resume an agent on it;
  the live session id is the resumed id, turn numbering and derived
  history continue from the loaded log. sessionPersistence is NOT
  hard-injected (non-persistent demos still work); resume rejects with a
  typed error when it is absent. assertAgentIdFree runs before any
  session is created (and again after the load await) so a duplicate id
  never leaves an orphaned live session.

Adds the runtime dsh-session-persistence dependency to agent-loop.

Tianyi Cui 43f4258277 Implement the agent loop plugin
@deepseek-ai/dsh-agent-loop: LoopAgent (inbox with queued + steering
FIFOs, per-step AbortController) and the streaming-first
session/turn/step loop. Extension seams: agent/request,
agent/step-result, agent/turn-continuation waterfalls; raw chunks
logged for replay while BlockAssembler builds the assembled message;
steering drains between steps; session/flush awaited at turn end.

16 tests with a scripted mock adapter cover turn lifecycle ordering,
tool round-trips, steering, inject(), continuation override/veto,
mid-stream abort, queued turn chaining, replay equivalence, and
mid-turn fiber disposal (HMR safety).
