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)

+# Haskell Bots
+
+These bots must be built as part of the `simplex-chat` cabal project.
+
+## Setup
+
+1. Clone simplex-chat (stable branch):
+   ```bash
+   git clone https://github.com/simplex-chat/simplex-chat.git
+   cd simplex-chat
+   git checkout stable
+   ```
+
+2. Copy bot directories into `apps/`:
+   ```bash
+   cp -r simplex-deadmans-bot simplex-chat/apps/
+   cp -r simplexxx-directory  simplex-chat/apps/
+   ```
+
+3. Add the following executables to `simplex-chat.cabal`:
+
+### simplex-deadmans-bot
+```cabal
+executable simplex-deadmans-bot
+  main-is: Main.hs
+  hs-source-dirs: apps/simplex-deadmans-bot
+  build-depends:
+    base, simplex-chat, simplexmq, text, stm, time, http-conduit
+  default-language: Haskell2010
+  ghc-options: -threaded
+```
+
+### simplexxx-directory
+```cabal
+executable simplexxx-directory
+  main-is: Main.hs
+  hs-source-dirs: apps/simplexxx-directory
+  other-modules:
+    Directory.BlockedWords, Directory.Captcha, Directory.Events,
+    Directory.Listing, Directory.Options, Directory.Search,
+    Directory.Service, Directory.Store, Directory.Store.Migrate,
+    Directory.Store.Postgres.Migrations, Directory.Store.SQLite.Migrations,
+    Directory.Util
+  build-depends:
+    -- same as simplex-directory-service in simplex-chat.cabal
+  default-language: Haskell2010
+  ghc-options: -threaded
+```
+
+4. On macOS, add to `cabal.project`:
+   ```
+   package *
+       extra-lib-dirs: /opt/homebrew/opt/openssl@3/lib
+       extra-include-dirs: /opt/homebrew/opt/openssl@3/include
+   ```
+
+5. Build:
+   ```bash
+   cabal update
+   cabal build simplex-deadmans-bot simplexxx-directory
+   ```
