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 044 - Typography Baseline
+
+## Goal
+Define the shared typography tokens and map them into Tailwind so text sizing stays consistent with the UI spec.
+
+## Prerequisites
+- Task 043 complete (color variables migrated).
+
+## Acceptance Criteria
+- [ ] `src/styles/tokens.css` includes typography variables (font families, weights, line heights, size scale).
+- [ ] `tailwind.config.js` `theme.extend.fontFamily` and `theme.extend.fontSize` reference the new variables.
+- [ ] `src/index.css` applies body font and default text color using the new variables.
+- [ ] No existing components lose readability or spacing.
+
+## Steps
+1. Add typography variables to `src/styles/tokens.css`, e.g., `--font-family-sans`, `--font-size-body`, `--line-height-body`.
+2. Extend Tailwind font families and sizes to match the variable names (`font-body`, `font-heading`, `text-body`, `text-label`).
+3. Update `src/index.css` body rules to use `var(--font-family-sans)` and the appropriate default sizes.
+4. Spot-check components for any stray font-size declarations that should use utilities instead.
+
+## Testing Checklist
+- [ ] Run `npm run dev` and verify the app renders without layout shifts.
+- [ ] Inspect headings, labels, and body text to make sure sizes align with the design doc.
+
+## Dependencies
+- Depends on Task 043.
+- Blocks Task 045 (component migration batch 1).
+
+## Estimated Time
+0.5 hours
+
+## Notes
+- Keep variable names semantic; record any design clarifications in the Notes section of the PR.
+- Use browser dev tools to confirm computed font values match expectations (14px body, 16px headers, etc.).
