[Feature]: Allow ZeroClaw to send messages to a channel

[daniel-sarosi-gwc]

Summary

ZeroClaw should be able to send messages to a telegram Channel

Problem statement

Currently, I can only send a telegram message to my ZeroClaw from Telegram, but not back to Telegram. For example, I have a range sensor on my Raspberry Pi. If someone gets within a certain range, I want to be notified on Telegram.

Proposed solution

Allow for messages to be sent with a command.

zeroclaw channel message "Someone is near your device." --channel-id channel-telegram

Non-goals / out of scope

Do not include all channels. Telegram would be fine for the first iteration.

Alternatives considered

No response

Acceptance criteria

• An event on my device can trigger a telegram message

Architecture impact

Channels

Risk and rollback

For loop scripts could generate DDoS attacks for telegram.

Breaking change?

No

Data hygiene checks

• I removed personal/sensitive data from examples, payloads, and logs.
• I used neutral, project-focused wording and placeholders.
