Fix lychee-detected broken links in CI

- Correct relative path in .github/ISSUE_TEMPLATE/version-bump.md (../../ not ../)
- Drop broken file link to scripts/qwen_embed_server_v3.py in Part 10; describe as local install path
- Add lychee.toml to exclude templates/ (placeholder user-vault paths) and ephemeral URL patterns
