feat: Continue CLI Git AI integration for tracking AI-authored code

[svarlamov]

Description

Add native integration with git-ai to help Continue CLI users track which lines of code were written by Continue CLI, along with the prompts used to generate them. The integration is only enabled if the user has git-ai installed on their machine already.

Checklist

• I've read the contributing guide
• The relevant docs, if any, have been updated or created
• The relevant tests, if any, have been updated or created

Screen recording or screenshot

Example editing session in a git repo with Continue CLI (no apparent changes for the user):

But since we had git-ai installed on the system, after we commit, we can run git-ai show head to see what Git AI recorded:

Tests

• Added extensions/cli/src/services/GitAiIntegrationService.test.ts unit tests to test the Git AI service
• Added extensions/cli/src/tools/gitAiIntegration.test.ts integration tests to test the entire tool calling flow with the git AI service
• Existing tests pass without changes

Summary by cubic

Integrates Continue CLI with git-ai to record which lines were generated by the CLI and the prompts that produced them. Works automatically when git-ai is installed, with no changes to the CLI workflow.

• New Features
  • Added GitAiIntegrationService that checks git-ai availability and sends checkpoint events via stdin.
  • Emitted PreToolUse/PostToolUse around file edits (Edit, MultiEdit, Write) from executeToolCall.
  • Sends session_id, transcript_path, cwd, file_path, and model (when known); scoped to the repo cwd.
  • Soft-fails: no-ops when git-ai is missing or errors occur, and never blocks tool execution.

^{Written for commit f3668ad. Summary will update automatically on new commits.}

✅ No documentation updates needed.

Analysis:

• Git AI integration is transparent (auto-detects if git-ai is installed)
• Removed artifact upload feature was never documented in user-facing docs
• No user-facing behavior changes requiring documentation
