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)

+# Task 048 - Message Stream & Tool Call Refactor
+
+## Goal
+Finish migrating the message stream container, tool call blocks, and reasoning UI to Tailwind utilities and shared tokens.
+
+## Prerequisites
+- Tasks 045-047 complete (message item, prompt input, and tabs refactored).
+
+## Acceptance Criteria
+- [ ] `src/components/message-stream.tsx`, `src/components/message-part.tsx`, and tool call subcomponents no longer depend on legacy classes (`.message-stream`, `.tool-call-message`, `.tool-call`, `.tool-call-header`, `.tool-call-preview`, `.tool-call-details`, `.reasoning-*`, `.scroll-to-bottom`, etc.).
+- [ ] Global CSS definitions for these selectors are removed from `src/index.css`, replaced by Tailwind utilities and token-aware helpers.
+- [ ] Scroll behavior (auto-scroll, “scroll to bottom” button) and collapsing/expanding tool calls behave as before in light/dark modes.
+- [ ] Markdown/code blocks continue to render properly within the new layout.
+
+## Steps
+1. Inventory remaining global selectors in `src/index.css` associated with the stream/tool-call UI.
+2. Update component markup to use Tailwind classes, creating shared helpers in `src/styles/components.css` when patterns repeat.
+3. Remove or rewrite the corresponding CSS blocks in `src/index.css` to avoid duplication.
+4. Validate tool call states (pending/running/success/error), reasoning blocks, and markdown rendering visually.
+
+## Testing Checklist
+- [ ] Run `npm run build`.
+- [ ] In dev mode, stream a message with tool calls and reasoning to ensure toggles and scroll helpers work.
+
+## Dependencies
+- Depends on prompt input and tab refactors to reduce merge conflicts.
+- Unlocks subsequent layout cleanups for logs and empty states.
+
+## Estimated Time
+1.25 hours
+
+## Notes
+- Branch suggestion: `feature/task-048-message-stream-refactor`.
+- Capture short screen recording or screenshots if tool call layout adjustments were required.
+- Legacy `message-stream.tsx` has since been replaced by `message-stream-v2.tsx` using the normalized message store.
