feat(slack): add userToken for read-only access to DMs and private channels (#981)

- Add userToken and userTokenReadOnly (default: true) config fields - Implement token routing: reads prefer user token, writes use bot token - Add tests for token routing logic - Update documentation with required OAuth scopes User tokens enable reading DMs and private channels without requiring bot membership. The userTokenReadOnly flag (true by default) ensures the user token can only be used for reads, preventing accidental sends as the user. Required user token scopes: - channels:history, channels:read - groups:history, groups:read - im:history, im:read - mpim:history, mpim:read - users:read, reactions:read, pins:read, emoji:read, search:read

+## User token (optional)
+Clawdbot can use a Slack user token (`xoxp-...`) for read operations (history,
+pins, reactions, emoji, member info). By default this stays read-only: reads
+prefer the user token when present, and writes still use the bot token unless
+you explicitly opt in. Even with `userTokenReadOnly: false`, the bot token stays
+preferred for writes when it is available.

-## Config writes
-By default, Slack is allowed to write config updates triggered by channel events or `/config set|unset`.
+User tokens are configured in the config file (no env var support). For
+multi-account, set `channels.slack.accounts.<id>.userToken`.

-This happens when:
- Slack emits `channel_id_changed` (e.g. Slack Connect channel ID changes). Clawdbot can migrate `channels.slack.channels` automatically.
- You run `/config set` or `/config unset` in Slack (requires `commands.config: true`).

 {
-  channels: { slack: { configWrites: false } }

+      appToken: "xapp-...",
+      botToken: "xoxb-...",
+      userToken: "xoxp-..."
+    }
+  }
 }
 ```

+Example with userTokenReadOnly explicitly set (allow user token writes):
+```json5
+{
+  channels: {
+    slack: {
+      enabled: true,
+      appToken: "xapp-...",

+    }
+  }
+}
+```
+
+### Token usage
+- Read operations (history, reactions list, pins list, emoji list, member info,
+  search) prefer the user token when configured, otherwise the bot token.
+- Write operations (send/edit/delete messages, add/remove reactions, pin/unpin,
+  file uploads) use the bot token by default. If `userTokenReadOnly: false` and
+  no bot token is available, Clawdbot falls back to the user token.

+- Writes default to the bot token so state-changing actions stay scoped to the
+  app's bot permissions and identity.
+- Setting `userTokenReadOnly: false` allows the user token to be used for write
+  operations when a bot token is unavailable, which means actions run with the
+  installing user's access. Treat the user token as highly privileged and keep
+  action gates and allowlists tight.
+- If you enable user-token writes, make sure the user token includes the write
+  scopes you expect (`chat:write`, `reactions:write`, `pins:write`,
+  `files:write`) or those operations will fail.

 - Mention gating is controlled via `channels.slack.channels` (set `requireMention` to `true`); `agents.list[].groupChat.mentionPatterns` (or `messages.groupChat.mentionPatterns`) also count as mentions.
