Batch extraction of every remaining subcommand whose handler is top-level and
whose parser block is pure argparse: model, setup, postinstall, whatsapp, slack,
login, logout, auth, status, webhook, hooks, doctor, security, dump, debug,
backup, import, config, version, update, uninstall, dashboard, gui, logs,
prompt-size.
Each becomes hermes_cli/subcommands/<name>.py with build_<name>_parser() and an
injected handler (no main import). dashboard also injects cmd_dashboard_register
for its nested 'register' action.
Behavior-neutral: all 25 subcommands' --help output (and nested subaction help)
diff-verified byte-identical to pre-extraction. Two RawDescriptionHelpFormatter
epilogs (debug, logs) needed their multi-line string interiors preserved at
column 0 — caught by the --help diff, not compile.
main() 3297 -> 1798 LOC across this PR; add_parser calls in main.py 179 -> 89.
Validation: tests/hermes_cli/ 6476 passed / 0 failed under per-file process
isolation; new test_subcommands_batch.py smoke-tests all 25 builders + the
dashboard two-handler case.
