fix(lpb): complete --help flag list, correct install.sh usage, dedupe env

- lpb.py --help: add --version, --yes, --non-interactive, --ssh-port,
  VSCodium dir flags (--data-dir/--user-data-dir/--ext-dir/--base-path)
- install.sh usage: plain lpb starts a Pi CLI session (not VSCodium);
  --without-token hides the token, does not disable auth
- lpb.conf.env: remove duplicated LPB_PERSIST_GH_CONFIG line
