Bug Description

The typing indicator TTL (time-to-live) is not refreshed when startTypingLoop() is called while the typing loop is already running. This causes the typing indicator to stop after 2 minutes even if tools are still executing.

Steps to Reproduce

1. Send a message that triggers a long-running tool (e.g., browser navigation, file operations)
2. Observe that typing indicator shows initially
3. After ~2 minutes, typing indicator stops even though the agent is still working

Root Cause

In src/auto-reply/reply/typing.ts, startTypingLoop() only calls refreshTypingTtl() when starting a new loop. If the loop is already running (typingTimer exists), it returns early without refreshing the TTL.

Proposed Fix

Move refreshTypingTtl() earlier in startTypingLoop() so it's called even when the loop is already running, while still respecting the runComplete guard.
