Feature Request

I hope that ai-commit can allow users to define custom instructions for generating commit messages.

This would function similarly to GitHub Copilot Chat's github.copilot.chat.commitMessageGeneration.instructions in settings.json.

Motivation

This feature would enable users to enforce specific commit conventions (e.g., Gitmoji, Conventional Commits) by providing rules for language, header format, and supported types, and available scopes. This will significantly improve accuracy and reduce manual edits.

Proposed Implementation

Add a new option to ai-commit's configuration, like so:

{
  "ai-commit.INSTRUCTIONS": [
    { "text": "Write Commit Messages in English." },
    { "text": "Commit Message Header Format: `<gitmoji> <type>(<scope>): <subject>`." },
    { "text": "Supported Types: ✨ feat, 🐛 fix, ♻️ refact, 📝 docs, 🎨 style, 📦️ build, 🧪 test, 🔧 chore, ⏪️ revert." }
  ]
}

Ai-commit should then use these instructions when generating suggestions.
