Codecov flagged 12 lines in crates/wickra-core/src/indicators/smma.rs
(file at 86.81%): the const accessors period (57-59), value (62-64)
and the Indicator-impl bodies warmup_period (95-97), name (103-105).
None of the existing tests inspected the metadata surface — they only
fed numeric updates and asserted on SMMA values.
Add accessors_and_metadata exercising period == 7, warmup_period == 7,
name == "SMMA", and value() across both the None (pre-warmup) and
Some (post-warmup) branches.
smma.rs is now at 91/91 lines, no behavioural change.
