Add comprehensive docstrings to the top-level CLI endpoints and helpers,
explaining the purpose and structure of each (sub)command.
Deats,
- add detailed docstring to `pikerd()` explaining its role as the
root service-actor/daemon supervisor.
- add docstring to `cli()` noting it's the root endpoint generally
requiring a sub-cmd input.
- add extensive docstring to `services()` explaining the daemon naming
conventions and listing a few current/common service actors.
- add docstring to `_load_clis()` explaining dynamic CLI loading.
Stylin,
- add multiline style to `and not maddrs` conditional in
`load_trans_eps()`.
- drop commented-out `--tsdb` and `--es` click options from
`pikerd()`, they're more or less obsolete given `nativedb`.
- add type annots where obviously handy.
- add TODO comment about UDS support in `services()`.
