chore: normalize line endings to LF via .gitattributes

Root-cause fix for mixed CRLF/LF in the repo (no .gitattributes previously).
Adds '* text=auto eol=lf' and explicit binary rules so all future checkouts
are LF. Renormalizes all tracked text files (no logical content change).

## Style Guidelines
**Style:** Warm Tech Minimalism
**Keywords:** clean, precise, data-dense, soft surfaces, indigo accent, generous whitespace
**Best For:** AI PaaS consoles, developer platforms, agent/workflow editors
**Key Effects:** Subtle hover lift (translateY -1 to -2px), 150-300ms ease transitions, soft shadow escalation, skeleton shimmer for loading, fade/slide micro-entrances.
### Page Pattern
**Pattern Name:** App Shell + Dashboard Grid
- **Conversion Strategy:** Core value shown immediately via workspace/chat; primary action (新建对话/部署) persistent in header and sidebar.
- **CTA Placement:** Sticky header + sidebar primary action; contextual CTAs inside cards.
- **Section Order:** Sidebar > Workspace(Chat/Agents/Skills/MCP) > Main content grid > Detail drawer

## Anti-Patterns (Do NOT Use)
- ❌ Ornate decoration
- ❌ Low contrast text
- ❌ Missing focus states
- ❌ Emojis as icons
- ❌ Layout-shifting scale hovers
- ❌ Instant state changes
### Additional Forbidden Patterns
- ❌ **Emojis as icons** — Use SVG icons (Heroicons, Lucide, Simple Icons)
- ❌ **Missing cursor:pointer** — All clickable elements must have cursor:pointer
- ❌ **Layout-shifting hovers** — Avoid scale transforms that shift layout
- ❌ **Low contrast text** — Maintain 4.5:1 minimum contrast ratio
- ❌ **Instant state changes** — Always use transitions (150-300ms)
- ❌ **Invisible focus states** — Focus states must be visible for a11y
