their SKILL.md content. Add caching to avoid repeated ZIP extraction.

Add POST /api/skills/install endpoint to install .skill files from
thread's user-data directory. The endpoint extracts the ZIP archive,
validates SKILL.md frontmatter, and installs to skills/custom/.
Frontend Install buttons now call the API instead of downloading.

Backend:
- Simplify citations prompt format and rules
- Add clear distinction between chat responses and file content
- Enforce full URL usage in markdown links, prohibit [cite-1] format
- Require content-first approach: write full content, then add citations at end
Frontend:
- Hide <citations> block in both chat messages and markdown preview
- Remove top-level Citations/Sources list for cleaner UI
- Auto-remove <citations> block in code editor view for markdown files
- Keep inline citation hover cards for reference details
This ensures citations are presented like Claude: clean content with inline reference badges.

When using thinking-enabled models (like Kimi K2.5, DeepSeek), the API
expects reasoning_content on all assistant messages. The original
ChatDeepSeek stores reasoning_content in additional_kwargs but doesn't
include it when making subsequent API calls, causing "reasoning_content
is missing" errors.
This adds PatchedChatDeepSeek which overrides _get_request_payload to
restore reasoning_content from additional_kwargs into the payload.
