Add file tools (readFile, listFiles, searchFiles) to the AI backend with multi-step support via stopWhen, and render tool invocations as collapsible inline elements in assistant messages. - Add createFileTools() with readFile, listFiles, searchFiles tools - Enable multi-step tool calling with stopWhen: stepCountIs(5) - Preserve UIMessage parts through the Message type and chat provider - Create ToolInvocation component for inline tool call display - Render tool parts interleaved with text in MessageContent
Parse <<<<<<< SEARCH / ======= / >>>>>>> REPLACE markers into color-coded added/removed lines with gutter indicators instead of showing raw diff syntax.

- Code blocks in chat collapse to ~4 lines with gradient fade and expand toggle, with a shimmer bar while streaming - Fix shouldTreatAsContext being too aggressive — now requires 2+ signals instead of any single match like a bare parenthesis - Modularize code-block into diff.ts, use-syntax-highlighting.ts, and collapsible-code.tsx

Summary
stopWhen: stepCountIs(5)shouldTreatAsContextwas too aggressive — normal text with parentheses or 3 lines would become a context tab. Now requires 2+ signals to triggerChanges
