Bug: Discord plugin permission requests cannot be approved from Discord

Plugin: discord@claude-plugins-official v0.0.4

Summary

When Claude triggers a permission request (e.g. for the reply tool), the server sends a Discord DM with Allow/Deny buttons. However, approving from Discord has no effect — only the CLI prompt works.

Root Cause (two issues)

1. No interactionCreate handler

server.ts sends Discord messages with button components:

new ButtonBuilder().setCustomId(`perm:allow:${request_id}`) ...
new ButtonBuilder().setCustomId(`perm:deny:${request_id}`) ...

But there is no client.on('interactionCreate', ...) handler anywhere in the file. Button clicks are silently ignored.

2. request_id is never shown to the user

The message content is just 🔐 Permission: <tool_name>. The request_id is only embedded in the button customId, never visible to the user — making the text-based yes XXXXX path impossible too.

Expected Behavior

Clicking Allow or Deny in Discord should approve or deny the permission request.

Suggested Fix

Add an interactionCreate handler that:

1. Checks if the interaction is a button with customId matching perm:allow:* or perm:deny:*
2. Extracts the request_id
3. Emits notifications/claude/channel/permission with the appropriate behavior
4. Acknowledges the interaction
