--all: every CDB record except __default__.
Optionalbbox--bbox <south>,<west>,<north>,<east>: a geo union predicate (device GPS in box).
--default: the reserved __default__ record.
Repeatable --group <name>.
Optionalnear--near <lat>,<lon>,<radius>: a geo union predicate (device GPS within radius).
Literal/lookup positionals (NOT operation args — the caller splits those).
OptionalquickchrRepeatable --quickchr <name>: quickchr machine names (the named-live-
provider, #134). Exclusive in v1 — a selection targets quickchr machines OR
CDB/literals, never both; the CLI enforces the usage error before expansion
and expandSelection re-asserts it.
Repeatable --where attr=value, AND-combined.
The parsed target selection a command hands to expandSelection.
