hermes - 💡(How to fix) Fix Feature: Add auto-delete option for tool status messages on Telegram

Problem

When Hermes sends tool status messages (e.g. 🔧 patch: "/Users/.../FEEDBACK.md") to Telegram, they persist in the chat forever. For quick operations (file patches, reads, etc.) these intermediate messages clutter the conversation after the final reply arrives.

Proposed Solution

Add a delete_after config option (in seconds) for tool status messages on the Telegram platform:

# In config.yaml
telegram:
  delete_tool_messages_after: 10  # auto-delete tool status messages after 10s, 0 = disabled (default)

Behavior:

• After the final reply is sent, schedule deletion of all tool status messages from that turn after the configured delay
• Default: 0 (disabled, current behavior — messages persist)
• Uses Telegram's deleteMessage API to remove the messages
• If the delay has already passed by the time the final reply lands, delete immediately

Alternatives Considered

• display.tool_progress = false — hides tool messages entirely, but loses visibility into what is happening during long operations. Some users want to see progress but then clean up.
• Per-tool-type config — more flexible but over-engineered for the use case.

Additional Context

Tool status messages are useful for transparency during execution, but become noise once the agent final answer is delivered. Auto-delete gives the best of both worlds: visibility during work + clean chat after.
