Restored from origin/main (b4663fb):
- .github/ workflows and issue templates
- .gitignore (proper exclusions)
- .opencode/agent/web_developer.md
- AGENTS.md, BUILD.md, PROGRESS.md
- dev-docs/ (9 architecture/implementation docs)
- docs/screenshots/ (4 UI screenshots)
- images/ (CodeNomad icons)
- package-lock.json (dependency lockfile)
- tasks/ (25+ project task files)

Also restored original source files that were modified:
- packages/ui/src/App.tsx
- packages/ui/src/lib/logger.ts
- packages/ui/src/stores/instances.ts
- packages/server/src/server/routes/workspaces.ts
- packages/server/src/workspaces/manager.ts
- packages/server/src/workspaces/runtime.ts
- packages/server/package.json

Kept new additions:
- Install-*.bat/.sh (enhanced installers)

+title: Long Paste Handling
+description: Summarize large pasted text into attachments.
+---
+
+Implement Long Paste Handling
+
+---
+
+### Detect Long Pastes
+
+Monitor clipboard paste events for text content. Identify if the pasted text exceeds a defined length (e.g., >150 characters or >3 lines).
+
+---
+
+### Create Summarized Attachments
+
+If a paste is identified as "long", prevent direct insertion into the input field. Instead, create a new text attachment containing the full content.
+
+Display a summarized chip for the attachment, such as `[pasted #1 10+ lines]`.
+
+---
+
+### Acceptance Criteria
+
+- Pasting short text directly inserts it into the input.
+- Pasting long text creates a summarized attachment chip.
+- The full content of the long paste is retained within the attachment for submission.
+- Multiple long pastes create distinct numbered chips.
