Add git update-ref completions

[SkyNotSilent]

Warp issue warpdotdev/warp#12322 requests completions for git update-ref, including workflows like:

git fetch origin
git update-ref --no-deref HEAD refs/remotes/origin/main
git read-tree HEAD
git checkout-index -fa
git clean -fd

The command-signatures package should add git update-ref metadata and complete full Git ref names such as refs/remotes/origin/main for the ref/value arguments.

Here's what I found while triaging this issue:

Thanks for the clear request. The Git completions currently do not include git update-ref, so this is actionable as an enhancement to add the command metadata and full-ref suggestions.

Maintainer details

I concluded that feature request to add command-signature support for git update-ref, including full Git ref-name completions for ref/value arguments..

Triage summary

This is an actionable enhancement request to add git update-ref completions. The report asks for command metadata for git update-ref and full Git ref-name suggestions such as refs/remotes/origin/main for ref/value positions.

Evidence

• command-signatures/json/git.json does not currently include an update-ref subcommand.
• Existing Git generators in command-signatures/src/generators/git.rs cover commits, tags, local branches, remote branches, and shortened remote branch names, but they do not expose full ref names in the refs/... form requested here.
• git update-ref -h confirms the command accepts forms like <refname> <new-oid> [<old-oid>], -d <refname> [<old-oid>], and --stdin, with options including --no-deref.

Likely implementation area

Add an update-ref subcommand entry to the Git spec and add or reuse a Git generator that can suggest complete ref names from git for-each-ref --format="%(refname)" for the ref-name arguments. Object/value arguments may also want existing revision/commit-style generators where appropriate.

Duplicate check

I checked all open issues plus recently closed issues and did not find two or more likely duplicates.

This is my automated analysis and may be incorrect. A maintainer will verify the details.

This is the same request as warpdotdev/warp#12322, which points to command-signatures for implementation. I opened PR #286 with the completion spec and ref generator. Could a maintainer please confirm this issue and mark it ready-to-implement if the approach is acceptable? Once marked, I can re-trigger Oz review with /oz-review.
