* Word-aligned longest common prefix. Doesn't chop mid-word. * Case-insensitive comparison (PowerShell: Git === git), emits first * string's casing. * ["npm run test", "npm run lint"] → "npm run" * ["Git status", "git log"] → "Git" (first-seen casing) * ["Get-Process"] → "Get-Process"

(strings: string[])

 * ["Get-Process"] → "Get-Process"
