* feat(ai): add Grok CLI as a Desktop no-API-key provider
Add grok-cli alongside Codex/Claude Code/Pi, with path/env settings,
isolated MCP-scoped headless runs, model listing, and connection test.
* feat(ai): expose Grok CLI reasoning effort like Codex
Attach low/medium/high effort capabilities to Grok models for the
assistant effort menu, wire resolve_model_effort for grok-cli, and
use the monochrome Grok mark icon.
* i18n: add Grok CLI error messages for remaining locales
Fill grokCli* cliErrors strings in es, it, ja, ko, pt-BR, and zh-TW
to match en/zh-CN and satisfy i18n autofill CI.
* fix(ai): align Grok CLI headless with official Build flags
Address review feedback on PR #5494:
- Use streaming-json + CliAgentJsonlDialect::GrokStreamingJson
- Switch permission to --always-approve and MCPTool(dbx__*) rules
- Prefer --effort over --reasoning-effort; keep --prompt-file
Verified with unit tests and a local headless e2e against grok 1.0.
* style(ai): fix rustfmt for Grok CLI provider files
* test(ai): fix Grok CLI entry in provider ordering spec
* fix(ai): harden grok CLI error wording and config schema
Add 'not signed in' to classify_grok_run_error and test_grok_connection
auth detection — real @xai-official/grok 1.0.0 emits this exact wording
on headless auth failure (verified against the shipped binary).
Remove invalid config.toml fields: permission_mode='always-approve'
(not a valid enum; auto-approve is driven by --always-approve flag) and
startup_timeout_sec/tool_timeout_sec/enabled_tools (not mcp_servers
schema fields per 'grok mcp add').
