Fix default embedding model in README and enforce LF line endings

[carlos-alm]

Summary

• Fix README models table incorrectly marking minilm as the default embedding model — the actual default is jina-code (as set in config.js, embedder.js, and cli.js)
• Add .gitattributes with * text=auto eol=lf to prevent CRLF line endings on Windows, which were causing 32 Biome format errors
• CI workflow hardening: validate version input, resilient publish steps, fix deps:tree script

Test plan

• Verify npm run lint passes clean
• Verify README models table shows jina-code (default)
• Confirm .gitattributes enforces LF on fresh clone

Greptile Summary

This PR fixes a documentation error in the README and adds line ending enforcement to prevent formatting issues. The README incorrectly labeled minilm as the default embedding model when the actual default is jina-code (verified in config.js:22, embedder.js:58, and cli.js:312).

Key changes:

• Corrected README models table to show jina-code as default
• Added .gitattributes with eol=lf to prevent CRLF issues that cause Biome format errors on Windows
• Improved publish workflow to stage only version bump files (package.json, package-lock.json, CHANGELOG.md, DEPENDENCIES.md) instead of using git add -A, preventing build artifacts from being committed to release branches

Confidence Score: 5/5

• This PR is safe to merge with no risk
• All changes are straightforward documentation fixes and configuration improvements with no functional code changes. The README correction matches the actual default values in the codebase, .gitattributes properly enforces LF line endings to prevent platform-specific formatting issues, and the workflow change prevents unintended file commits.
• No files require special attention
