refactor: drop redundant ServiceLoader constructors (S1186)

All 73 S1186 "empty method" hits were explicit public no-arg
constructors on the codec classes (EncodingDecoder/EncodingEncoder
impls and the extension singletons). They are redundant: a public
class with no declared constructor already has an implicit public
no-arg constructor, which is exactly what ServiceLoader needs — so
the empty bodies are deleted rather than commented. Simplify-first:
remove code, kill the smell at the root, no unkillable comment.

EncodingTableFitnessTest (ServiceLoads every decoder/encoder) stays
green, proving discovery is unaffected; full verify green.
