restore: recover deleted documentation, CI/CD, and infrastructure files

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)
- Launch-*.bat/.sh (new launchers)
- README.md (SEO optimized with GLM 4.7)

+title: Image Clipboard
+description: Support pasting images from the clipboard.
+---
+
+Implement Image Clipboard Support
+
+---
+
+### Detect Image Paste
+
+Detect when image data is present in the system clipboard during a paste event.
+
+Prioritize image data over text data if both are present.
+
+---
+
+### Create Image Attachment
+
+Automatically create an image attachment from the pasted image data. Convert the image to a base64 encoded format for internal handling and submission.
+
+Display the image attachment as a chip in the input area.
+
+---
+
+### Acceptance Criteria
+
+- Pasting an image from the clipboard creates an image attachment chip.
+- The image data is base64 encoded and associated with the attachment.
+- The attachment chip has a suitable display name (e.g., `[Image #1]`).
+- Users can clear the image attachment.
