4.13.2: packaging fix - exclude Wasm/repro scratch + bundle precompiler tool

Wrapper-only fix over 4.13.1 (forks unchanged at 2.0.27, no library code change):
- Razor SDK was sweeping Wasm/repro/**/*.json (manifest/stats/sitemap debugging
  scratch) into the package as content/+contentFiles/; excluded Wasm\repro\** from packing.
- The precompiled-shaders precompiler tool (tools/) is gated behind
  -p:PackPrecompilerTool=true, which the publish path never passed -> 4.13.0/4.13.1
  shipped without it. Release pack now passes the flag; tool is bundled from 4.13.2 on.

4.13.0/4.13.1 stay on nuget.org (immutable); 4.13.2 supersedes them.

+## 4.13.2 (2026-06-16) - Packaging fix (no code changes)
+
+Wrapper-package-only fix over 4.13.1 (forks unchanged at `2.0.27`). No library/runtime behavior changed.
+
+- **Removed stray content from the package.** The Razor SDK was auto-sweeping `*.json` files from the tracked `Wasm/repro/` debugging-repro tree (V8 barrier-bug repros) into the nupkg as `content/` + `contentFiles/` - 18 junk `manifest.json`/`stats.json`/`sitemap.json` files with no business in the shipped library. Excluded `Wasm\repro\**` from packing.
+- **Bundled the precompiled-shaders precompiler tool (`tools/`).** Layer 2 of the precompiled-shaders feature - the precompiler worker + its dependency closure - is gated behind `-p:PackPrecompilerTool=true`, which the publish bat never passed, so 4.13.0 and 4.13.1 shipped without it (the opt-in feature errored for consumers, pointing at the absent tool). `_publish-nuget.bat` now re-packs with that flag before pushing, and the tool is present from 4.13.2 on.
+- 4.13.0 / 4.13.1 remain on nuget.org (immutable); 4.13.2 supersedes them. Use 4.13.2.

 ## 4.13.1 (2026-06-16) - FP8 radix-sort keys on all 6 backends
 
 ### FP8 (Float8E4M3 / Float8E5M2) radix-sort keys

-		<PackageReleaseNotes>4.13.0 brings full low-precision floating-point support across ALL 6 backends (CPU, OpenCL, WebGPU, WebGL, Wasm, CUDA): Half, BFloat16, and now FP8 (Float8E4M3 + Float8E5M2), plus generic INumber&lt;T&gt; mixed-precision kernels and PrecisionConvert for transpilable generic float&lt;-&gt;T conversion inside a kernel. This release also fixes bf16 on PRE-AMPERE CUDA cards (GTX 1080 / RTX 2060 etc.): the PTX bf16 path used sm_80+ cvt instructions and failed to compile on older cards; it now uses portable bit-manipulation that works on every CUDA architecture (FP8 likewise).
