feat: agent concurrency, conversation summaries, AI tools config, UI polish

- Agent slot limiter for concurrent tool execution - Conversation summarization with soft-delete (MarkSummarized) - ANSI stripping in terminal tool output - Configurable crush-run timeout (default 600s, max 900s) - Starship theme refactor, AI tools config grid, system update UI - Streaming segments refactor, summarized messages block in feed - CSS: headings, scrollbars, tool cards, summary block styles - i18n additions (en+fr) for tools, updates, config 💘 Generated with Crush Assisted-by: GLM-5.1 via Crush <crush@charm.land>
