* Control: name the token file and spot a stale one when a call is unauthorized (#4664)
When the app refuses a token that the MCP client read from a token file,
the error now names that file, when it was written and how long ago,
without printing the token. The app also writes `<port>.pid` beside the
token file (its process id and, on Linux, its start time) and removes
both at exit; when that process has exited, the error says the token
file is stale. The process check runs only after a refusal, and the
token file itself stays one line, so existing clients keep working.
Document force-quit leftovers and the MSIX AppData redirection.
