Initial commit: bots, AI-parameterised support bot, web frontend

- simplex-deadmans-bot: Dead Man's Switch Haskell bot
- simplexxx-directory: private SimpleXXX directory bot (fork of simplex-directory-service)
- simplex-support-bot: support triage bot with configurable AI backend
  - --ai-url and --ai-model flags for any OpenAI-compatible provider
  - works with Grok, Ollama, OpenAI, LM Studio, etc.
  - AI_API_KEY env var (GROK_API_KEY still accepted as alias)
- web: SimpleXXX directory frontend (Groups/Channels tabs, matches simplex.chat/directory style)
- manager/: placeholder for Python profile manager (coming soon)
