 - Tools: add Firecrawl fallback for `web_fetch` when configured.
 - Tools: send Chrome-like headers by default for `web_fetch` to improve extraction on bot-sensitive sites.
 - Tools: Firecrawl fallback now uses bot-circumvention + cache by default; remove basic HTML fallback when extraction fails.
+- Tools: default `exec` exit notifications and auto-migrate legacy `tools.bash` to `tools.exec`.
 - Status: trim `/status` to current-provider usage only and drop the OAuth/token block.
 - Directory: unify `clawdbot directory` across channels and plugin channels.
