fix(cli): strip launch-global flags before non-launch subcommands

`resolveCliArgv` hoisted a subcommand hidden behind leading global launch
flags to the front and forwarded those flags to the subcommand's own
parser (#2970). Launch-shaped commands (`launch`/`acp`) share the launch
flag surface, but strict-parsing subcommands like `update` declare only
their own flags, so a leading `--cwd` reached `node:util.parseArgs` and
threw `Unknown option '--cwd'`. This bit users whose shell alias/wrapper
runs `omp --cwd <dir> update`.

Leading launch-global flags are now stripped when the hoisted subcommand
is not launch-shaped, and still forwarded for `launch`/`acp`. Shared the
launch-command set with the profile bootstrap to keep one source of truth.

Fixes #8891
