Teknium 3f95e741a7 fix: validate empty user messages to prevent Anthropic API 400 errors (#3322) ...

When user messages have empty content (e.g., Discord @mention-only
messages, unrecognized attachments), the Anthropic API rejects the
request with 'user messages must have non-empty content'.

Changes:
- anthropic_adapter.py: Add empty content validation for user messages
  (string and list formats), matching the existing pattern for assistant
  and tool messages. Empty content gets '(empty message)' placeholder.

- discord.py: Defense-in-depth check at gateway layer to catch empty
  messages before they enter session history.

- Add 4 regression tests covering empty string, whitespace-only,
  empty list, and empty text block scenarios.

Fixes #3143
