Add branch configuration documentation for main as default branch

[Copilot]

Overview

This PR adds comprehensive documentation to guide repository maintainers and contributors in using main as the default branch for the FoodRecipe_app repository.

Current Status

The repository is already in good shape:

• ✅ The main branch exists and contains all the code
• ✅ No master branch exists (nothing to remove)
• ✅ All development is properly organized on main

Changes Made

1. Created Branch Configuration Guide (docs/BRANCH_CONFIGURATION.md)

A comprehensive 120+ line guide that provides:

• Step-by-step instructions for setting main as the default branch on GitHub
• Procedures for removing a master branch if it exists elsewhere
• Commands for updating local repositories after branch changes
• Best practices and recommendations for branch management
• Links to official GitHub documentation

2. Added Quick Reference Guide (docs/QUICK_REFERENCE.md)

A concise quick-start document with:

• Current repository status summary
• Clear action items for repository owners (with direct links)
• Commands for team members to update their local clones
• Verification procedures

3. Updated README.md

Enhanced the README with:

• Proper git clone instructions using code blocks
• Clear note in the Contributing section about main being the default branch
• Link to the branch configuration documentation

What Repository Owners Need to Do

There's one remaining step that requires repository admin access and must be done through GitHub's web interface:

Set the default branch to main on GitHub:

1. Visit https://github.com/souravk29/FoodRecipe_app/settings
2. Navigate to the "Default branch" section under General settings
3. Click the switch/pencil icon next to the current default branch
4. Select main from the dropdown menu
5. Click "Update" and confirm the change

This ensures:

• New pull requests automatically target main
• New repository clones checkout main by default
• GitHub's UI displays main as the primary branch

Impact

• No application code changes - Only documentation added
• No breaking changes - All modifications are additive
• No new dependencies - No libraries or build tools introduced
• Improved contributor experience - Clear guidance on branch usage

Documentation

All information is available in:

• Quick start: docs/QUICK_REFERENCE.md
• Detailed guide: docs/BRANCH_CONFIGURATION.md
• Contributing section: README.md

Note: This PR addresses the request to make main the default branch. The repository already uses main and has no master branch, so the primary need is documentation and GitHub settings configuration.
