Changed libraries by category/area

Collections / data structures

• dictionaries: splay-tree implementation; new lookup/4 returning splayed tree.
• sets: treap implementation.
• heaps: pairing heap implementation; fixed valid/1 for binary heaps.
• listp/list/difflist: added take/4.

Randomness / IDs / stats / math

• random: added SplitMix64, Xoshiro*, WELL512a support.
• uuid: added UUIDv7 support, uuid_nil/1, uuid_max/1 (RFC 9562).
• statistics: added percentile/quartiles/correlation/moments/error metrics and more.
• natural: added factorial/2, binomial/3.
• numberlist: added linear_regression/4.
• dates: added substantial date/time conversion and duration predicates.
• arbitrary + types: added text and text(CharSet); backend compatibility/portability fixes.

Data formats / parsing

• csv and tsv: optional comment support.
• json and json_lines: fixed unused dependencies.

Functional/error-handling abstractions

• expecteds: many new conversion/mapping/composition predicates.
• optionals: many new conversion/mapping/composition predicates.
• expecteds + optionals: added QuickCheck shrinking support.
• validations: introduced as complementary accumulated-error model to expecteds fast-fail style.

Networking / integration

• redis: added common operation wrappers; updated to use new sockets compatibility library.

Portability cleanups

• Reduced portability warnings in arbitrary, os, random, types and tools loading paths on specific backends.

Non-library notable changes

• Compiler/runtime: stricter create_object/4 and create_category/4 argument checks; multiple fixes for include/1, initialization/1, and predicate_property/2 runtime-bound cases.
• Tools: new help::man/1 predicate; tester/doclet scripts now print runtime and improved formatting/accuracy.
• IDE support: VSCode test results now include per-entity and per-predicate coverage data.
