feat: make Sequence.all() and Sequence.any() return actual predicate values instead of booleans

Rewrite all() and any() to store and return the predicate's result directly, matching && and || semantics. Update documentation to describe the new behavior. Move tests from test/core/list/ to test/core/sequence/ and add cases verifying that the first falsey/truthy value is returned.
