Add curated high-value prompts registry + smoke-test and README

[CHINGBOH]

This PR adds a curated set of high-value prompts extracted from the last year's conversation artifacts for the Layered Prompt Engine. Files included:

• 00-项目/01-RAG_and_Agents/01-知识库检索系统/提示词工程/additions/high_value_prompts_registry_full.yaml (full 50-entry registry)
• 00-项目/01-RAG_and_Agents/01-知识库检索系统/提示词工程/additions/high_value_prompts_registry.yaml (small example)
• 00-项目/01-RAG_and_Agents/01-知识库检索系统/提示词工程/additions/smoke_test_render.py (smoke-test runner for /api/layered/debug/prompt)
• 00-项目/01-RAG_and_Agents/01-知识库检索系统/提示词工程/additions/README_HIGH_VALUE_PROMPTS.md (instructions + usage)

Notes / status:

• I was unable to add the CI workflow file at .github/workflows/prompt_smoke_test.yml via API (received 404). The workflow contents are available locally and in the patch at /tmp/high_value_prompts_patch.diff if maintainers prefer to add it to the repo.
• The smoke-test runner targets the debug endpoint /api/layered/debug/prompt and will write results to /tmp/layered_prompt_smoke_results.json. This can be run locally or via a manual workflow run once the service is reachable.

If maintainers prefer, I can split these additions into smaller PRs, or prepare entry-by-entry migrations into the production prompts.yaml.

Thanks — please let me know if you want metadata (tags, origins, or provenance) added to the registry entries before merging.
