The engine-owned esys_move (#65) reads Position/Body/Collider/Solids by name,
but no package defined them — every game and example re-declared identical
bundles by hand. Ship them as the source package ludic.core; games import
instead of copy-pasting, and extend by composition (attach their own
components on the same model). AOT → compiles into the consumer's ECS with no
seam; integer + Q16.16 deterministic. Adds examples/library/core_components
(driven by esys_move, composed with a game Health component) as a
controller_case (104/0).
