Support interactive Mode

[appleboy]

CodeGPT currently automatically generates commit titles and content, but if users want to modify the title or content, they need to adjust the relevant information through Git commands. Could it support Interactive Mode, allowing CodeGPT to generate the title first for the user to confirm before proceeding so that users can make modifications without using other methods directly?
