* fix(scripts): drop HAS_GIT from PowerShell git-extension output (parity with bash)
create-new-feature-branch.ps1 emitted a HAS_GIT key in its JSON output and a 'HAS_GIT:' line in text output that the bash twin never emits. The bash output contract is {BRANCH_NAME, FEATURE_NUM} (+ DRY_RUN) only, so a tool parsing the machine-readable output got a different shape on Windows/PowerShell vs macOS/Linux -- a cross-platform contract divergence.
$hasGit is still computed and used internally for branch-creation logic; only its two output emissions are removed, restoring parity. Added regression tests asserting neither the PS nor the bash output contains HAS_GIT (JSON and text). Noted as a follow-up in #3129.

* docs: note DRY_RUN in the HAS_GIT-omission comment (parity)
Address Copilot review: the comment described the output contract as {BRANCH_NAME, FEATURE_NUM} without mentioning that DRY_RUN is still conditionally added in JSON mode on dry runs. Clarify so the contract description is complete for future maintainers. Comment-only.

Git Branching Workflow Extension
Git repository initialization, feature branch creation, numbering (sequential/timestamp), validation, remote detection, and auto-commit for Spec Kit.
Overview
This extension provides Git operations as an optional, self-contained module. It manages:
- Repository initialization with configurable commit messages
- Feature branch creation with sequential (
001-feature-name) or timestamp (20260319-143022-feature-name) numbering - Branch validation to ensure branches follow naming conventions
- Git remote detection for GitHub integration (e.g., issue creation)
- Auto-commit after core commands (configurable per-command with custom messages)

Configuration
Configuration is stored in .specify/extensions/git/git-config.yml:
# Branch numbering strategy: "sequential" or "timestamp"
branch_numbering: sequential
# Custom commit message for git init
init_commit_message: "[Spec Kit] Initial commit"
# Auto-commit per command (all disabled by default)
# Example: enable auto-commit after specify
auto_commit:
default: false
after_specify:
enabled: true
message: "[Spec Kit] Add specification"
Installation
# Install the bundled git extension (no network required)
specify extension add git
Disabling
# Disable the git extension (spec creation continues without branching)
specify extension disable git
# Re-enable it
specify extension enable git
Graceful Degradation
When Git is not installed or the directory is not a Git repository:
- Spec directories are still created under
specs/ - Branch creation is skipped with a warning
- Branch validation is skipped with a warning
- Remote detection returns empty results
Scripts
The extension bundles cross-platform scripts:
scripts/bash/create-new-feature-branch.sh— Bash implementation (branch creation only)scripts/bash/git-common.sh— Shared Git utilities (Bash)scripts/powershell/create-new-feature-branch.ps1— PowerShell implementation (branch creation only)scripts/powershell/git-common.ps1— Shared Git utilities (PowerShell)
