v0.28.1

• Let a path address many nodes: a bare * segment expands to every child, so reading one field across a collection is 'values FILE package.*.name' instead of enumerating, appending the field to each address with sed, and reading them back
• BREAKING: * is a legal JSON key, so the grammar gains * alongside . and \ and join_path escapes stars — paths now prints * where it printed *, and a bare * is refused rather than read as a key, so one spelling keeps one meaning
