Fix CI test failures for path normalization and redaction

Resolves two critical CI failures:

1. **Test redaction in CI**: Fixed VITEST env var handling to enable
   redaction in CI while protecting production builds. Removed VITEST
   from Rollup's inlining list so it reads from runtime environment,
   and added logic to default to false in published builds unless
   explicitly set to true.

2. **Windows path normalization**: Fixed inconsistent path separators
   in npm/paths module by maintaining forward slashes consistently
   across all platforms using string concatenation instead of path.join(),
   which was creating mixed separators on Windows.
