Add Windows Terminal installer (install.ps1 / install.bat)
install.ps1 copies bash.exe to %LOCALAPPDATA%\Programs\BashForWindows, adds it to the user PATH, and injects a "Bash for Windows" profile into Windows Terminal's settings.json so the shell appears in the + dropdown. install.bat is a double-click wrapper that bypasses the PS execution policy. build.sh --release produces a release/ folder ready to zip and distribute. Supports -Uninstall flag to cleanly remove everything. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

.SYNOPSIS
|
||||
Installs bash-for-windows and registers it as a Windows Terminal profile.
|
||||
.DESCRIPTION
|
||||
Copies bash.exe to a permanent location, adds it to the user PATH,
|
||||
and adds a "Bash for Windows" entry to Windows Terminal so it appears
|
||||
in the new-tab dropdown.
|
||||
.EXAMPLE
|
||||
.\install.ps1
|
||||
.\install.ps1 -InstallDir "$env:APPDATA\BashForWindows"
|
||||
.\install.ps1 -NoPath -NoTerminal
|
||||
.\install.ps1 -Uninstall
