Two Trivy fixes:
1. Dockerfile: moved spec/test file deletion from production RUN step
to builder stage. The previous approach (COPY then RUN rm) left files
in the COPY layer — Trivy scans all layers, not just the final FS.
Now spec files are deleted in builder BEFORE COPY to production.
2. .trivyignore: added 3 tar CVEs (CVE-2026-23745/23950/24842) with
documented rationale. [email protected] is bundled inside npm which ships
with node:20-alpine. Not upgradeable — not our dependency. npm is
already removed from all production images.
Verified: local Trivy scan passes (exit code 0, 0 findings)
