First release candidate for the 0.1.0 chart. Chart content is identical to the upcoming 0.1.0. The RC exists to dry-run the release pipeline: OCI push to ghcr.io/robintra/charts/perf-sentinel, Cosign keyless signing via the GitHub OIDC token, SLSA level 3 provenance on the tarball, draft GitHub Release with both the .tgz and the .intoto.jsonl as assets.
Promote to 0.1.0 once the RC's OCI artifact verifies clean via cosign verify and slsa-verifier verify-artifact.
