Add comprehensive git commit editing documentation and tools

[Copilot]

This PR addresses the need for clear guidance on how to edit commits in the OVMS Android project by providing comprehensive documentation and practical tools.

What's Added

📖 Comprehensive Documentation (EDITING_COMMITS.md)

A detailed 318-line guide covering all commit editing scenarios:

• Amending recent commits (message changes, adding/removing files)
• Interactive rebase for editing older commits
• Squashing and splitting commits
• Recovery procedures when things go wrong
• OVMS Android project-specific best practices

⚡ Quick Reference (COMMIT_EDITING_QUICK_REF.md)

A concise cheat sheet for the most common commit editing operations, perfect for developers who need quick reminders.

🔧 Interactive Demo Script (demo-commit-editing.sh)

An executable script that demonstrates safe commit editing practices with:

• Status checking utilities
• Backup creation strategies
• Command previews without making actual changes
• Recovery options and safety tips

📝 Updated Main Documentation

Enhanced the main README.md to reference the new commit editing documentation, making it easily discoverable for contributors.

Key Features

Safety First Approach: All documentation emphasizes creating backups before complex operations and provides recovery procedures.

Project-Specific Guidance: Examples tailored to Android development workflows, including integration with Gradle builds and following the project's commit message conventions.

Practical Examples: Real-world scenarios like preparing commits for pull requests, cleaning up feature branches, and handling common mistakes.

Usage

Developers can now:

# Quick reference for common operations
cat COMMIT_EDITING_QUICK_REF.md

# Run interactive demo to learn safely
./demo-commit-editing.sh

# Follow detailed step-by-step instructions
open EDITING_COMMITS.md

This documentation will help both new and experienced contributors work more effectively with git commits while maintaining the project's high standards for commit quality and history cleanliness.

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
