Workflows enabled by default; tool controls via config.toml

Workflows now enabled by default. Users can disable image generation and video generation tools via config.toml or environment variables. /session-info displays whether session uses OAuth or API key. grok doctor fix commands can run directly from TUI. !cmd commands allow up to one hour before timing out. Startup warnings point to /doctor for details. Dashboard hover and clicks no longer miss gaps between items. Shift/Alt+Enter inserts newline while editing queued prompt. Queued prompt edits under combine mode no longer lose changes. Forking session with compaction no longer causes rewind failures. Permission prompts correctly move focus when viewing scrollback. Pressing Esc once cancels current agent turn. Grok stops turns that repeat same tool call many times. Background subagent completion messages no longer leak into unrelated sessions. Auto-permission classifier timeout shows normal permission prompt instead of silently denying. Managed MCP tools no longer time out prematurely. Voice dictation on macOS uses less memory with temporary helper process.
