ACP (Agent Client Protocol) Overhaul

This release focuses on making sub-agent orchestration fluid, responsive, and robust.

Highlights

Event-Driven Completion

• Replaced 500ms polling in waitAll()/waitTasks() with EventEmitter-based resolution for instant completion detection.
• SubagentManager now emits typed lifecycle events: task:queued, task:started, task:completed, task:failed and task:chunk.

Live Streaming from Sub-Agents

• Sub-agent output is now streamed to the TUI in real-time with labeled, dimmed text blocks.
• Status indicators show start/complete/fail with duration for each sub-agent

Real-Time Progress Tracking

• StatusBar displays live orchestration progress (ACP [2/5 done, 1 running, 2 queued]) instead of a generic "thinking..." spinner
• Progress updates on every lifecycles transition including task:started

Incremental Result Streaming

• Results are emitted to the user as each sub-agent finishes - no more waiting for all to complete.
• Synthesis LLM call is now conditional: only triggered when there are failures, eliminating unnecessary latency.

Abort & Cancellation

• AgentLoop gains abort() with AbortController support, checked before each iteration and tool execution.
• New cancelTask() / cancelAll() methods on SubagentManager with proper guard against double-finalization.
• Subagent tool exposes cancel and cancel_all actions
• News config option: acpCancelOnFailure.

Optimized Spawning

• spawnMany() now uses Promise.all for parallel spawning
• Session pre-warming pool eliminates synchronous DB writes from the spawn critical path.
• All event listeners are registered before spawning to prevent missed early events.
