- Change default CPS install path on Windows from `cps` to `cps/<name>`,
per community recommendation that only paths containing the package name
should be considered as "officially" supported search locations (see
https://github.com/cps-org/cps/issues/79#issuecomment-2831102822).
- Change `export` to write to a subdirectory that allows the build
tree to be used as a search root.
- Change SBOM destinations to be consistent with the preceding.
