v0.10.11 — ACP v2 lifecycle and background continuations

ACP v2 lifecycle and background continuation hardening

• Derive ACP v2 Running and Idle from authoritative logical-turn lifecycle events, eliminating phantom no-work turns.
• Preserve paired lifecycle state across tools, approvals, cancellation, errors, retries, and background suspension.
• Resume pending background work through task-manager wakeups while keeping tool transcripts provider-valid.
• Harden ACP prompt ownership, cancellation races, accepted-prompt failures, and autonomous inference cancellation.
• Carry full detached results as structured notifications with bounded text summaries.
