Summary

Modernizes the Git Command Palette quick wizards with a cleaner architecture and improved user experience.

Impact

• Improves progress tracking with scope-based indicators instead of step counting
• Breaks down large monolithic commands (Branch, Stash, Remote, Tag, Worktree) into focused sub-commands
• Fixes step reset issues during wizard transitions (e.g., creating a worktree then opening it)

Validation

• Test branch creation, deletion, rename via command palette
• Test stash push, apply, pop, drop, rename flows
• Test remote add, remove, prune operations
• Test worktree creation and subsequent open step

Risk

Medium - Major refactoring of command structure. E2E tests added to verify wizard transition flows.
