fix: add language-specific README files for npm and crates.io

[konard]

Summary

• Create language-specific README.md files for each implementation:
  • js/README.md: JavaScript/npm-specific documentation with installation and API usage
  • rust/README.md: Rust/Cargo-specific documentation
  • Root README.md: Common overview linking to both implementations
• Remove README copy step from CI workflow (no longer needed)
• Remove js/README.md from .gitignore (now tracked in git)

Approach (per feedback)

Instead of copying the root README during npm publish, we now maintain separate documentation:

1. Common README.md (root): Language-agnostic overview with links to implementations
2. js/README.md: Full JavaScript/npm documentation with installation, quick start, API reference
3. rust/README.md: Full Rust/Cargo documentation with installation, examples, API reference

This approach:

• Provides appropriate documentation for each package manager
• Eliminates the need for copying files during CI
• Allows each implementation to have tailored documentation

Test plan

• Verified locally with npm pack --dry-run that README.md (8.8kB) is included in tarball
• CI lint and format checks pass

Fixes #19

As we now have two saparate language versions, I think we should have README.md files in both JS and Rust forlders, and have common README.md that is not specific to any of these languages.

So we should have common README.md, and language specific ones that will go directly to their respective package managers.

I don't like the idea of just coping README.md file.

🤖 Solution Updated

Based on the feedback about having separate README files for each language implementation, the solution has been revised:

Changes Made

1. Root README.md - Now language-agnostic overview with:

   • Table of available implementations (JS and Rust with package badges)
   • Core concept explanation (page state machine)
   • Page trigger lifecycle description
   • Links to language-specific READMEs

2. js/README.md (new file) - JavaScript/npm-specific documentation with:

   • npm installation instructions
   • Quick start with JavaScript examples
   • Full API reference
   • Best practices

3. rust/README.md (new file) - Rust/Cargo-specific documentation with:

   • Cargo.toml installation instructions
   • Quick start with Rust examples
   • API reference for Rust types

4. CI workflow - Removed the README copy step (no longer needed)

5. .gitignore - Removed js/README.md entry (now tracked in git)

Verification

• ✅ npm pack --dry-run confirms README.md (8.8kB) is included in the npm tarball
• ✅ JS CI/CD Pipeline passed
• ✅ Rust CI/CD Pipeline passed

The PR is now ready for review.
