* feat(javascript): report observed export property presence Extend compare_javascript_export_shapes so each retained return variant lists observed property names and each change reports presence independently of value resolution. Complete parent coverage classifies one-sided names as added or removed even when static values stay unknown. Fixes #725 * test(javascript): match unknown export-shape values by availability Nested availability objects include a reason when values stay unresolved. Assert availability through objectContaining so presence-only added and removed rows still verify unknown values. * fix(javascript): preserve uncertain export property presence and locations * fix(javascript): normalize presence and preserve local property coverage * fix(javascript): require present discriminants for return pairing * fix(javascript): normalize retained shapes before comparison * refactor(javascript): share return projection with executable examples * fix(javascript): localize uncertainty for missing mutated slots * fix(javascript): bind advertised export examples to exact artifacts * fix(javascript): keep uncertain property flow as candidates --------- Co-authored-by: morluto <76467478+morluto@users.noreply.github.com>
