hermes - 💡(How to fix) Fix [Feature]: Add option to ignore @all/@everyone mentions in Feishu group chats

Problem Description

Currently, Hermes Bot in Feishu always responds when someone uses @所有人 (everyone mention), even if the bot is not explicitly mentioned. This is hardcoded behavior in the Feishu adapter:

# gateway/platforms/feishu.py:4093-4097
def _mentions_self(self, message: Any) -> bool:
    # @_all is Feishu's @everyone placeholder.
    raw_content = getattr(message, "content", "") or ""
    if "@_all" in raw_content:
        return True  # ← Hardcoded, always triggers bot

In many enterprise/group scenarios, @所有人 is used for general announcements (e.g., system notifications, team updates) that don't require bot intervention. The bot responding to every @所有人 creates noise and is often unwanted.

Proposed Solution

Add a configuration option to control whether @所有人 triggers the bot:

Option 1: Environment Variable

FEISHU_IGNORE_MENTION_ALL=true

Option 2: YAML Config

feishu:
  ignore_mention_all: true

Implementation

Modify _mentions_self() in gateway/platforms/feishu.py:

def _mentions_self(self, message: Any) -> bool:
    raw_content = getattr(message, "content", "") or ""
    
    # Check ignore_mention_all config
    if not self._ignore_mention_all:
        if "@_all" in raw_content:
            return True
    
    # ... rest of the logic

Use Cases

1. Enterprise groups: @所有人 is frequently used for company-wide announcements where bot intervention is not needed
2. Notification groups: Groups dedicated to system alerts/notifications where bot should only respond to explicit @botname mentions
3. Multi-purpose groups: General discussion groups where @所有人 is used for important human-to-human communication

Current Workaround

None. The behavior is hardcoded and cannot be configured.
