'claw prompt --help' was triggering an API call instead of showing help
because --help was parsed as part of the prompt args. Now '--help' after
known pass-through subcommands (prompt, login, logout, version, state,
init, export, commit, pr, issue) sets wants_help=true and shows the
top-level help page.
Subcommands that consume their own args (agents, mcp, plugins, skills)
and local help-topic subcommands (status, sandbox, doctor) are excluded
from this interception so their existing --help handling is preserved.
156 CLI tests pass, fmt clean.
