Handle + force-push prefix in git push branch completion

[lucieleblanc]

Summary

Handle the + force-push prefix in git push origin +<branch> branch name completion.

Previously, typing git push origin +fo<TAB> would not show any completions because the + prefix was included in the token matched against branch names, and no branch starts with +.

Changes

Generator changes (git.rs)

• Added push_refspec_branches and push_refspec_tags generators using command_from_tokens
• These detect the + prefix in the current token and use a marker-based approach to signal the post-processing callback to prepend + to all suggestions
• Helper functions: with_force_prefix_detection(), strip_force_prefix(), prepend_to_suggestions()

Spec changes (git.json)

• Changed the push subcommand's refspec arg from ["local_branches", "tags"] to ["push_refspec_branches", "push_refspec_tags"]

Tests

• Added 4 tests covering branches and tags with and without the force prefix

APP-3488 [git] Handle + prefix in git push origin +<branch>

git push origin +fo<TAB> — the + prefix (force-push syntax) breaks branch name completion. The completer/parser doesn't strip the + prefix before matching against branch generators.

See GitHub #5225

Generator Validation Screenshots

Tested the push_refspec_branches and push_refspec_tags generators locally by patching warp-internal to use the local command-signatures checkout on this branch.

Test 1: git push origin <Tab> (without + prefix)

Shows branches and tags as normal completions (master, bugfix/auth-error, feature/dashboard, feature/login, v1.0.0, v2.0.0).

Test 2: git push origin +<Tab> (with + force-push prefix)

Shows branches and tags with + prefix for force-push (+master, +bugfix/auth-error, +feature/dashboard, +feature/login, +v1.0.0, +v2.0.0).

Both generators work correctly ✅
