Feature: Channel-level quiet mode via bot mention

[BillChirico]

Summary

Add a "quiet mode" feature where users can temporarily silence the bot in a specific channel by mentioning it with a command like @Bot quiet.

Proposed Behavior

Command

• Mention the bot with keywords like: quiet, shush, silence, stop
• Example: @Volvox Bot quiet for 30 minutes

Permissions (Configurable)

• Default: Moderator role required
• Configurable via web dashboard: Can be set to "Anyone", "Moderator", or "Admin"
• Setting path: config.quietMode.allowedRoles — array of role IDs, or ["any"] for everyone
• Respects existing permission system (permissions.moderatorRoleId, permissions.adminRoleId)

Web Dashboard Configuration

New section in config editor:

{
  "quietMode": {
    "enabled": true,
    "allowedRoles": ["moderator"], // Options: ["any"], ["moderator"], ["admin"], or specific role IDs
    "defaultDurationMinutes": 30,
    "maxDurationMinutes": 1440
  }
}

UI Controls:

• Toggle: Enable/Disable quiet mode feature
• Select: Who can use it (Anyone / Moderator / Admin / Specific Roles)
• Number input: Default duration (minutes)
• Number input: Maximum allowed duration (minutes)

Duration

• Default: 30 minutes (configurable in dashboard)
• Max: 24 hours (configurable in dashboard)
• Format: @Bot quiet [for] [X] [minutes/hours]

Scope

• Per-channel only — does not affect other channels
• Bot continues to work normally in other channels
• Does not affect DM conversations

Restoration

• Automatically resume after duration expires
• Manual restore: @Bot unquiet or @Bot resume
• Shows remaining time if asked: @Bot status

Storage

• Store active quiet modes in Redis/memory with TTL
• Key format: quiet:{guildId}:{channelId}
• Value: { until: timestamp, by: userId }

Use Cases

• Meeting/channel-specific discussions where bot responses are distracting
• Temporary focus periods (code reviews, announcements)
• Community moderation without full bot disable

Acceptance Criteria

• Bot recognizes quiet/unquiet commands via mention
• Validates user has permission based on config.quietMode.allowedRoles
• Parses duration (respects default/max from config)
• Stores quiet state per-channel with expiration
• Resumes normal operation automatically after expiry
• Responds with confirmation message when quiet mode is set/removed
• Ignores all non-command messages during quiet period (except unquiet/status)
• Web dashboard UI for configuring permissions and defaults
• Config validation in configValidation.js
• Added to configAllowlist.js for web editing
