Gordon Lam 1e3429dd3a Introduce worktree helper scripts for faster multi-branch development in PowerToys (#42076)

## Summary of the Pull Request
This pull request introduces a new suite of helper scripts for managing
Git worktrees in the `tools/build` directory, along with comprehensive
documentation. The scripts streamline common workflows such as creating,
reusing, and deleting worktrees for feature branches, forks, and
issue-based development, making it easier for developers to work on
multiple changes in parallel without duplicating the repository. Each
script is provided as both a PowerShell (`.ps1`) and Windows batch
(`.cmd`) wrapper for convenience. A detailed markdown guide explains
usage patterns, scenarios, and best practices.

**New worktree management scripts:**

* Added `New-WorktreeFromFork.ps1`/`.cmd` to create a worktree from a
branch in a personal fork, handling remote creation and branch tracking
automatically.

* Added `New-WorktreeFromBranch.ps1`/`.cmd` to create or reuse a
worktree for an existing local or remote branch, with logic to fetch and
track branches as needed.

* Added `New-WorktreeFromIssue.ps1`/`.cmd` to create a new issue branch
from a base ref (default `origin/main`), slugifying the issue title for
branch naming.

* Added `Delete-Worktree.ps1`/`.cmd` to safely remove a worktree, with
options to force removal, keep the local branch, or retain orphan fork
remotes. Includes robust error handling and manual recovery guidance.

**Documentation:**

* Introduced `Wokrtree-Guidelines.md`, a comprehensive guide covering
the purpose, usage, flows, naming conventions, troubleshooting, and best
practices for the new worktree scripts.

.SYNOPSIS
Create (or reuse) a worktree for a new issue branch derived from a base ref.
.DESCRIPTION
Composes a branch name as issue/<number> or issue/<number>-<slug> (slug from optional -Title).
If the branch does not already exist, it is created from -Base (default origin/main). Then a
worktree is created or reused.
.PARAMETER Number
Issue number used to construct the branch name.
.PARAMETER Title
Optional descriptive title; slug into the branch name.
.PARAMETER Base
Base ref to branch from (default origin/main).
.PARAMETER VSCodeProfile
VS Code profile to open (Default).
.EXAMPLE
./New-WorktreeFromIssue.ps1 -Number 1234 -Title "Crash on launch"
.EXAMPLE
./New-WorktreeFromIssue.ps1 -Number 42 -Base origin/develop
.NOTES
Manual recovery:
git fetch origin
git checkout -b issue/<num>-<slug> <base>
git worktree add ../Repo-XX issue/<num>-<slug>
code ../Repo-XX
