Symbolics v7.38.0

Diff since v7.37.0

Added

• Documented API is enforced by a strict QA pass (#1957). The SymbolicUtils surface that
  using Symbolics provides is now an explicit export list rather than
  @reexport using SymbolicUtils. The list is a superset of what SymbolicUtils itself exports,
  so nothing that was reachable before has been withdrawn; scalarize, shape, unwrap and
  Unknown moved from @public to exported.

Fixed

• @register_array_symbolic no longer escapes a bare @wrapped into the calling module (#1972).
  Callers that did not happen to import Symbolics.@wrapped failed to precompile with
  UndefVarError: @wrapped not defined. This is what left MethodOfLines unable to load.
• Complex{Symbolics.Num} is inferred as ScalarSymbolic, matching Symbolics.Num.

Removed

• The obsolete SymbolicsPreallocationToolsExt extension (#1969); PreallocationTools 1.7 handles
  the symbolic cache dispatch natively, and the floor is raised to match. Reexport is no longer
  a dependency.

Known issues

• The new QA lane reports two pre-existing Aqua findings (a method ambiguity and a piracy). These
  predate this release; 7.37.0 shipped the same code with no QA lane to detect them.
