Merge main into fix/db-off-data-plane-469

Brings in the two commits main gained: #472 (CLI cleanup — remove `info`,
split `list active` into a top-level `active`, simplify `list`) and the
terminology glossary. #472 was written against the old flat cli/ layout,
so its semantics are reconciled into the reorg'd cli/commands/ structure:

  * new `active` command lives at cli/commands/active.py, registered in
    the lazy registry and listed in `help` (not left at the flat path).
  * `info` removed: deleted cli/commands/info.py, dropped from the
    registry and `help`.
  * `list` simplified to list-available-only, using the reorg's
    os.getcwd()/constants.PROG conventions.
  * the `list active` -> `active` doc wording applied to the backend
    docstrings that our split moved into base.py / selection.py.

Our reorg wins for the fully-rewritten dispatcher (cli/__init__ shim,
backend facade). pyright: 0 errors. Full unit suite green (2243).
