David Snelling 89e4d810ed docs: correct misleading SQ4 quantization comment in type definitions 
Two type-definition comments (src/coreTypes.ts:472 +
src/types/brainy.types.ts:1123) stated:

  bits?: 8 | 4   // default: 8 (SQ8). SQ4 requires cortex native.

This was factually wrong. src/utils/vectorQuantization.ts:412 ships
distanceSQ4Js, a pure-JS SQ4 implementation that's been part of the
open-core path the whole time. The native SIMD acceleration is a drop-in
via setSQ4DistanceImplementation, NOT a hard requirement.

The misleading comment risked pushing open-core users to assume they
needed a paid native provider for SQ4 quantization when they did not.

Corrected to:

  bits?: 8 | 4   // default: 8 (SQ8). SQ4 has a pure-JS implementation;
                 // cortex's distance:sq4 SIMD provider accelerates it.

Pure documentation; no behaviour change. Caught during an upstream
open-core-boundary audit (handoff thread BRAINY-8.0-RENAME-COORDINATION,
section E.1).

Verification

- npx tsc --noEmit: clean
- npm test: 1468 / 1468 unit
