Split the cli package's two responsibilities out of __init__:
* commands/__init__.py now assembles the COMMANDS registry and
NO_MIGRATION_COMMANDS from the per-command modules — the command
surface lives entirely under commands/.
* __main__.py now owns main() (dispatch + migration gate + exit-code
mapping) alongside the runnable entry guard.
cli/__init__.py shrinks to a shim that re-exports main / COMMANDS /
NO_MIGRATION_COMMANDS, so bot_bottle.cli.main (repo-root cli.py entry)
and the tests' bot_bottle.cli.COMMANDS keep working unchanged. Verified
`python -m bot_bottle.cli` (runpy) and `cli.py` both dispatch; full unit
suite green (2243).

`python -m bot_bottle.cli` failed with "is a package and cannot be
directly executed" — the package had a `if __name__ == "__main__"` block
in `__init__.py`, which never fires for a package and made the invocation
look supported when it wasn't. Add a real `__main__.py` and drop the dead
block.
Matters for `bb login`, whose docstring documents a `bb` entry point that
nothing installs; `-m` is the closest thing to it until there's a
console-script.
