* feat(git-refs): use dereferenced commit hash for annotated tags
When git ls-remote lists annotated tags, it returns two entries:
1. The tag object hash: refs/tags/v1.0.0 -> abc123
2. The dereferenced commit hash: refs/tags/v1.0.0^{} -> def456
Previously, Renovate used the tag object hash (abc123). However, `git submodule status` returns the actual commit hash (def456). This mismatch caused false-positive dependency updates that resulted in empty commits, since the tag object and commit hash differ even when pointing to the same version.
This feature:
- Parses both entries from git ls-remote into allRefs
- Builds a lookup map of tag names to their dereferenced commit hashes
- For annotated tags, replaces the tag object hash with the commit hash
- Lightweight tags are unaffected (they already return the commit hash)
This ensures Renovate's detected digest matches what git submodule operations actually use, preventing unnecessary update PRs.

You can use this datasource plus regex managers to update git-based dependencies that are not natively supported by Renovate.
The git-refs datasource returns a reference from a Git repository.
The packageName must be a fully qualified domain name.
To fetch the latest digest of a reference instead of the named reference: put the named reference in currentValue and match on the currentDigest.
Usage example
Say you want to maintain the HEAD digest of the master branch of a repository.
You would configure a custom manager in your Renovate config file for files named versions.ini:
{
"customManagers": [
{
"customType": "regex",
"managerFilePatterns": ["/^versions.ini$/"],
"matchStrings": ["GOOGLE_API_VERSION=(?<currentDigest>.*?)\\n"],
"currentValueTemplate": "master",
"depNameTemplate": "googleapis",
"packageNameTemplate": "https://github.com/googleapis/googleapis",
"datasourceTemplate": "git-refs"
}
]
}
