feat(primordials): expand surface (Function, Math) and adopt inline export const style

- Add FunctionPrototypeApply / FunctionPrototypeBind / FunctionPrototypeCall
  for callers that need to invoke user code with a controlled thisArg
  without going through globalThis (these are the common capture targets
  in socket-btm's safe-references.js).
- Add Math primordials: Abs, Ceil, Floor, Max, Min, Pow, Random, Round,
  Sign, Sqrt, Trunc. MathCeil specifically is used by socket-btm for
  block-size math that must not be monkey-patched during Node bootstrap.
- Convert the module from the `const X = …; export { X, Y, … }` two-step
  to inline `export const X = …`. Matches the style used elsewhere in
  socket-lib (src/errors.ts, src/objects.ts) and removes the large export
  block that was ~60 lines of boilerplate.
- Expand the unit-test suite from 17 tests to 64:
  - every exported primordial gets a functional test, not just a sample;
  - additional prototype-pollution resilience cases covering
    String.prototype.slice and JSON.parse alongside the existing
    Array.prototype.map / Array.isArray / Object.keys clobbering tests.

Bump to 5.26.0 (additive, no breaking changes).
