0.3.16: Multi-Turn Progress Tail Continuity, Cold Token Stamp Grace, And Eager Delivery Bind

• Multi-Turn Progress Tail Continuity: Fixed an issue where the live progress bubble became stale in multi-turn sessions (autonomous tasks, subagents, and sequential tool runs). progress-tail now maintains a single active bubble across turns with willContinue: true, decouples from publication reservation deadlock, and finalizes cleanly upon session settlement.
• Cold Token Stamp Grace: Fixed runtime-unavailable rejections on ask tool delivery caused by generation increments during initial token loading. createTelegramTransportStampRuntime now adopts the bot token on cold startup without bumping generation or invalidating initial transport stamps.
• Eager Delivery Runtime Startup: Bound delivery lifecycle runtime eagerly at extension load, ensuring sendTelegramView and ask are immediately functional even before session_start lifecycle events trigger.
• Resilient Thread Target Resolution: Enhanced proactivePushTargetGetter and delivery authorization to fallback to findCurrentThreadRecord()?.target, preventing thread ID loss when transient active turn state clears.
