Merge branch 'main' into feat/channel_enhancement

Keep the channel enhancements aligned with the current codebase while preserving a simpler product surface. This keeps QQ, Feishu, Telegram, and WhatsApp improvements together, removes the extra Telegram-only tool hint toggle, and makes WhatsApp mention-only groups actually work.

+
+If your channel requires interactive authentication (e.g. QR code scan), override `login(force=False)`:
+
+```python
+async def login(self, force: bool = False) -> bool:
+    """
+    Perform channel-specific interactive login.

+    # 2. Check if already authenticated (load from disk/state)
+    # 3. If not, show QR code and poll for confirmation
+    # 4. Save token on success
+```
+
+Channels that don't need interactive login (e.g. Telegram with bot token, Discord with bot token) inherit the default `login()` which just returns `True`.
+
+Users trigger interactive login via:
+```bash
+nanobot channels login <channel_name>
+nanobot channels login <channel_name> --force  # re-authenticate
