chore(web/shell): #107 code-quality review — an unused constant and a dead assignment go

links.js declared FILE (vscode.FileType.File) and never used it: the existence check compares the
stat's type with 'file'. input-parser.js set i = s.length right before the break that leaves the
loop, and nothing reads i after it. The input-parser and links suites pass unchanged.
