Generic HTTPS Git sync

Code Storage can now sync repositories from non-GitHub providers over generic HTTPS Git.

This covers providers like GitLab, Bitbucket, Codeberg, SourceHut, Gitea, and Forgejo. Instead of requiring a GitHub App-style integration, you create a repository with a baseRepo in sync mode and attach generic Git credentials for the upstream.

This is useful for teams running self-hosted Git, migrating repositories into Code Storage, or connecting to providers where standard HTTPS Git credentials are the right integration point.

const repo = await store.createRepo({
  id: 'my-gitlab-mirror',
  baseRepo: {
    provider: 'gitlab',
    owner: 'myorg',
    name: 'myrepo',
    operation: 'sync',
    upstreamHost: 'gitlab.example.com',
    defaultBranch: 'main',
  },
});

After the repository is created, attach credentials for the upstream repository:

curl -X POST https://code.storage/api/v1/repos/git-credentials \
  -H "Authorization: Bearer $REPO_WRITE_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "repo_id": "your-repo-id",
    "username": "git-user",
    "password": "git-password-or-token"
  }'

For providers with a default public host, Code Storage can derive the upstream URL automatically. If you are using a self-hosted instance, pass upstreamHost as a bare hostname like gitlab.example.com.

Generic HTTPS Git sync gives you the same base-repo sync model without depending on a provider-specific app installation flow.
