feat: AutoGenerate Commit Message in Git

[Ayyanaruto]

Description

This pull request adds an AI-powered "Generate Commit Message" feature to the VS Code extension, allowing users to automatically generate concise commit messages for staged Git changes using their configured chat model. The feature is fully integrated into the VS Code command palette and the Source Control (SCM) UI, with appropriate error handling and user prompts.

New Commit Message Generation Feature:

• Added a new command, continue.generateCommitMessage, to the extension's command palette and SCM title menu, visible when a Git repository is present.
• Implemented the command logic in commands.ts to:
  • Detect the active Git repository and ensure staged changes exist.
  • Use the selected chat model from the Continue configuration to generate a commit message based on the staged diff, following specific formatting rules (summary line and up to 5 bullet points).
  • Handle multiple repositories, prompt the user if a commit message is already present, and show progress/cancellation options.
  • Display errors and restore the original commit message if generation fails or is cancelled.
