chore(ruvector): bump to 0.2.32 (ADR-256 release prep) (#578)

* chore(ruvector): bump to 0.2.32 (harness router + default-deny MCP policy)

Release prep for the ADR-256 work merged in #575:
- `ruvector harness status [--json]` unified routing surface
- default-deny MCP tool policy (RUVECTOR_MCP_ALLOW/DENY/PROFILE)
- stable memory namespace (RUVECTOR_MEMORY_NAMESPACE)
- startup-budget CI guard

Additive / non-breaking → patch bump. Tests green (73/0, 8/0, 2/0).
Does NOT publish — `npm publish` left to a maintainer with npm auth.

* fix(ruvector): cross-platform build script (node fs.cpSync)

The build copied ONNX assets with `mkdir -p`/`cp -r`, which fail on Windows
cmd.exe and broke `npm publish` (prepack/prepublishOnly) off-Linux. Replace
with node fs.cpSync(recursive) — works everywhere. Verified: build + verify-dist
green on Windows (14 dist paths present).
