Changes Made

The following work has been completed and committed locally:

1. Added upstream remote - Configured @Floorp-Projects/Floorp-runtime as the upstream remote repository

Documentation

This PR includes comprehensive documentation to complete the setup:

• NORA_BRANCH_SETUP.md - Complete documentation of steps taken, verification commands, and instructions for pushing the branch
• push-nora-branch.sh - Executable script to push the nora-0.2.0 branch to origin

Manual Action Required

⚠️ Due to authentication constraints in the automated environment, the nora-0.2.0 branch has been created and committed locally but requires manual push to complete the setup.

To push the branch, run:

git push -u origin nora-0.2.0

Or use the provided script:

./push-nora-branch.sh

The branch is fully prepared with all changes committed - only the final push operation requires manual intervention with appropriate GitHub credentials.

Verification

Once pushed, the nora-0.2.0 branch will include all GitHub Actions workflows and configuration files necessary for building and maintaining the Floorp runtime project.

Verify locally with:

git log nora-0.2.0 --oneline -3
git ls-tree -r nora-0.2.0 -- .github/ | wc -l  # Should show 267

Original prompt
