Connect a new git repository. Three modes available:

api_only  — GitHub/GitLab REST API (no cloning). Best for cloud agents. Requires a credential with a PAT token.
sandbox   — Ephemeral compute container that clones, edits, and destroys. Supports test execution.
bridge    — Route operations through local Bridge daemon. Best for self-hosted repos.

provider is auto-detected from URL if not specified.
