Last ned hellogrok 0.1.1

Added
- Explicit search model selection via [models].web_search config key and GROK_WEB_SEARCH_MODEL environment variable, with env taking precedence over config.
- Hosted search capability auto-detection for Grok relay channels at startup (web_search + x_search probing).
- Chat Completions search dialect auto-detection (search_parameters vs web_search_options).
- CC Switch takeover detection before config rewrite — start is refused when CC Switch already owns Grok Build.
- Single-instance enforcement for both tray and foreground modes via OS-level lock.
- Windows log window application icon display in title bar and taskbar.
- Search route resolution logging at startup, visible in hellogrok routes and the log window.
Changed
- Tray now defaults to proxy-enabled on first launch.
- Tray quit defers exit when a config-ownership conflict exists, preventing orphaned proxy URLs.
- SIGINT/SIGTERM handlers retry stop on deferred errors instead of leaving the process inconsistent.
- BackendSearchSet field distinguishes explicit supports_backend_search declarations from Build's false default, enabling runtime probing for unset values.
- Route now carries HostedSearchKnown, HostedWebSearch, HostedXSearch, and HostedChatSearchDialect for capability-aware request normalization.
- Tool choice normalization is now capability-aware — only confirmed hosted search declarations are injected.
Fixed
- Managed search flag now placed after channel settings in config rewrites, preventing key-ordering issues.
- Client search wire alias properly hidden from upstream requests.
