* Remove silent prefix detection from args path in init
When explicit branch names containing slashes were passed to `gh stack
init` (e.g. `gh stack init myprefix/branch`), detectPrefix would
silently extract the prefix and store it in the stack config. This
caused `gh stack add otherbranch` to unexpectedly produce
`myprefix/otherbranch` without the user ever opting in.
Remove the automatic prefix detection from the args path so that
explicit branch names are taken literally. Users who want a prefix
should use `--prefix`. The interactive path (no args) continues to
prompt for confirmation before setting a prefix.
* Remove dead detectPrefix function and its tests
After removing the silent prefix detection from the args path,
detectPrefix has no production callers. Remove the function and
its table-driven unit test to avoid maintaining unused code.
