feat(telegram): add silent message option (#2382)

* feat(telegram): add silent message option (disable_notification)

Add support for sending Telegram messages silently without notification
sound via the `silent` parameter on the message tool.

Changes:
- Add `silent` boolean to message tool schema
- Extract and pass `silent` through telegram plugin
- Add `disable_notification: true` to Telegram API calls
- Add `--silent` flag to CLI `message send` command
- Add unit test for silent flag

Closes #2249

AI-assisted (Claude) - fully tested with unit tests + manual Telegram testing
