Pull request overview

This PR aligns the TypeScript implementations of @tolki/str and @tolki/num with updated Laravel-style semantics: containsAll() no longer treats an empty needle list as a successful match, and numeric humanization/abbreviation no longer emits a spurious "-0" for small negative values that round to zero.

Changes:

• Update Str.containsAll() (and thus Stringable#containsAll()) to return false when the needles iterable is empty, and add corresponding test coverage.
• Update Num.summarize() sign handling to avoid returning "-0" when the summarized magnitude equals zero at the requested precision, and add corresponding test coverage.
• Add changesets for both behavior fixes; update PHP stubs / function lists and a collections docs stub in support of framework parity/reference syncing.
