chore: reorganize root files

[ZhuLinsen]

What changed

• Move documentation image/design assets from sources/ to docs/assets/ and update README / docs image links.
• Move the Eastmoney request patch package from patch/ to src/patches/ and update data provider imports, Docker packaging, and CI smoke imports.
• Move CI-only backend dependencies from requirements-ci.txt to .github/requirements-ci.txt and update CI / PR review references.
• Move the skill-facing analyzer adapter from analyzer_service.py to src/services/analyzer_service.py and update SKILL.md examples.
• Mark moved documentation assets as binary in .gitattributes so PR review diff decoding does not choke on binary/design files.
• Add an [Unreleased] changelog entry for the repository-root cleanup.

Why

The repository root had accumulated implementation details, documentation assets, and CI-only files alongside the primary project entrypoints. This keeps the root focused on stable project-level files while preserving existing runtime behavior.

Impact

• Runtime imports now use src.patches.eastmoney_patch instead of patch.eastmoney_patch.
• Documentation image paths now point to docs/assets/.
• CI installs backend gate dependencies via .github/requirements-ci.txt, which includes the root runtime requirements with -r ../requirements.txt.
• GitHub PR review no longer tries to decode moved binary assets as UTF-8 diff content.

Validation

Local:

• python -m py_compile src/services/analyzer_service.py data_provider/efinance_fetcher.py data_provider/akshare_fetcher.py src/patches/eastmoney_patch.py .github/scripts/ai_review.py
• python -c "from src.services.analyzer_service import analyze_stock, analyze_stocks, perform_market_review; from src.patches.eastmoney_patch import eastmoney_patch; from data_provider.efinance_fetcher import EfinanceFetcher; from data_provider.akshare_fetcher import AkshareFetcher; print('moved imports ok')"
• Checked .github/requirements-ci.txt resolves ../requirements.txt
• python scripts/check_ai_assets.py
• ./scripts/ci_gate.sh syntax
• Verified PR-review-style git diff ... can be decoded with text=True

CI on PR #1257:

• ai-governance: pass
• backend-gate: pass
• docker-build: pass
• web-gate: skipped, no frontend changes
• PR Review static check, AI review, review report, security check, and labels: pass
