feat: self-heal continuation + auto-proceed session advancement

[aEgoist]

Patch 1: Self-heal continuation (go-on)

Problem

When a model API disconnects, returns empty content, or the AgentLoop exits a tool-call-only turn without producing a text reply, the session permanently stalls. The user must manually type "继续" (continue) to unblock.

Solution

• Detection: After a complete event, check the last assistant text message. If its trimmed content is < 20 characters, we consider the turn stalled.
• Action: Automatically send a "继续" command via startSessionCommand to resume the session.
• 10-second cooldown: Prevents duplicate triggers from multiple rapid completes.
• Opt-in setting: selfHealContinue (default false), toggled in Settings → Permissions.

Patch 2: Auto-proceed session advancement

Problem

Users need a way to keep sessions moving forward without manual re-prompting. After each assistant reply, the user must manually check whether the work is complete and type a follow-up instruction.

Solution

Auto-proceed — a per-session toggle that, when active, automatically sends a configurable follow-up prompt after each assistant reply, re-checking completeness and correctness. The session self-terminates when the assistant says "无需自动推进" (no auto-advance needed).

• Per-session toggle: Click the small dot beside each session title in the sidebar to toggle auto-proceed on/off.
  • 🟢 Emerald dot = auto-proceed active
  • ⚪ Gray dot = auto-proceed off
  • 🔵 Blue dot = unread messages (overrides green temporarily)
  • Spinner = agent running
• Global default: autoProceedOn setting (default true) controls whether new sessions start with auto-proceed enabled.
• Customizable prompt: autoProceedPrompt setting — the follow-up prompt injected after each reply.
• Self-termination: If the assistant replies with "无需自动推进", no further prompt is injected.
