Greptile Summary

Merges shuvcode-dev branch into integration, bringing upstream v1.1.25 sync along with critical fixes for SSH paste handling and the OPENCODE_DISABLE_MODELS_FETCH flag.

Key Changes:

• Upstream v1.1.25 Sync: Server routes modularization (split into 12 separate route files), edit project/session titles, unified search for commands and files, Carbonfox theme, MCP OAuth redirect URI configuration, skeleton loader for sessions, version display in session header, and LiteLLM proxy provider option
• SSH Paste Fix (fix: coalesce fragmented paste events over SSH #305): Addresses fragmented paste events from terminals like MobaXterm (already merged into shuvcode-dev before this PR)
• Models Fetch Flag Fix (fix: respect OPENCODE_DISABLE_MODELS_FETCH flag in ModelsDev.get() #307): Ensures OPENCODE_DISABLE_MODELS_FETCH properly prevents models.dev data from being used (already merged into shuvcode-dev before this PR)
• CSS Production Build Fix: Removed extra closing brace in message-part.css that was breaking Tailwind CSS parser during production builds
• Console Improvements: Replaced light-rays component with new WebGPU-based spotlight component, updated @smithy/eventstream-codec dependency
• Bug Fixes: Remember last opened project, truncate workspace title, plugin cache reinstall when module missing, question tool tab navigation

Architecture Impact:
The server routes refactoring is a significant architectural improvement that modularizes the monolithic server.ts into separate route files (session.ts, mcp.ts, file.ts, config.ts, experimental.ts, provider.ts, pty.ts, question.ts, permission.ts, global.ts, tui.ts). This improves maintainability and follows separation of concerns principles.

Testing:

• Typecheck passes (bun turbo typecheck)
• Existing tests cover changes
• SSH paste fix manually validated per PR description

Confidence Score: 5/5

• This PR is safe to merge with minimal risk
• This is a well-structured merge PR that brings upstream v1.1.25 changes plus critical fixes. The server routes refactoring follows clean separation patterns with no breaking changes to the API contract. The CSS fix resolves a production build blocker with a simple syntax correction. The fixes for SSH paste (fix: coalesce fragmented paste events over SSH #305) and models fetch flag (fix: respect OPENCODE_DISABLE_MODELS_FETCH flag in ModelsDev.get() #307) were already merged and validated in shuvcode-dev. All changes pass typecheck and are architecturally sound.
• No files require special attention
