(feat): Enhancements to Spec Kit

[localden]

Description

• Introduces a smoother hand-off between stages when used with GitHub Copilot in Visual Studio Code. Prompts are now effectively "shortcuts" for chat modes, and chat modes can then hand-off to specific post-production steps.
• Adds support for the version command. (specify --version flag not supported, returns error #486)
• Fixes Potential bug with the create-new-feature.ps1 script that ignores existing feature branches when determining next feature number #975
• Fixes Add graceful fallback and logging for GitHub API rate-limiting during template fetch #970

Version

References

• Built-in Planning workflow with explicit control to proceed to implementation or custom next steps microsoft/vscode#261542
• Allow chaining sequential workflows with chat modes and handoffs microsoft/vscode#272211

Behavior notes

• There is an unexpected behavior when hand-off occurs, resetting to Agent Mode. This will be fixed by the VS Code team.

tomllib is only available in Python 3.11+. While the project requires Python >=3.11 according to pyproject.toml, the import should be wrapped in a try-except block since it's already inside an exception handler and a fallback version of "unknown" is acceptable.

Suggested change

	import tomllib
	pyproject_path = Path(__file__).parent.parent.parent / "pyproject.toml"
	if pyproject_path.exists():
	with open(pyproject_path, "rb") as f:
	data = tomllib.load(f)
	cli_version = data.get("project", {}).get("version", "unknown")
	try:
	import tomllib
	except ImportError:
	# tomllib not available, fallback to "unknown"
	pass
	else:
	pyproject_path = Path(__file__).parent.parent.parent / "pyproject.toml"
	if pyproject_path.exists():
	with open(pyproject_path, "rb") as f:
	data = tomllib.load(f)
	cli_version = data.get("project", {}).get("version", "unknown")

[nitpick] The version string could be simplified using platform.python_version() which returns the same information in a cleaner way.

Suggested change

	info_table.add_row("Python", f"{sys.version_info.major}.{sys.version_info.minor}.{sys.version_info.micro}")
	info_table.add_row("Python", platform.python_version())

[nitpick] The regex pattern could be made more readable with a comment explaining that it removes Git's current branch marker (*), whitespace, and remote prefixes (e.g., 'remotes/origin/').

Suggested change

	# Clean branch name: remove leading markers and remote prefixes
	# Clean branch name: remove leading markers and remote prefixes
	# The following regex removes:
	# - Git's current branch marker ('*') and leading whitespace (e.g., '* main')
	# - Remote prefixes (e.g., 'remotes/origin/')

in vscode insiders i have a warning saying "Chat modes have been renamed to agents. Please move this file to .github/agents/speckit.[prompt].agent.md". should you not put this inside the new designated folder and file from vscode ?
