Sækja ORAS CLI 1.3.3

ORAS CLI v1.3.3 is a maintenance release focused on security hardening, dependency updates, and a few user-facing improvements to `oras attach`.

## Highlights

🔒 **Security:** upgraded `oras-go` to **v2.6.2**, which addresses a tar-extraction path-traversal advisory ([GHSA-fxhp-mv3v-67qp](https://github.com/advisories/GHSA-fxhp-mv3v-67qp)) affecting hardlink entries during `pull`/extract.
✨ **`oras attach` gains `--config`** support, and `--annotation $config:*` values now flow through to the packed manifest.
🛡️ **Supply-chain hardening:** GitHub Actions are now pinned to commit SHAs, SBOMs are attached to release artifacts, and static security scanning (gosec) runs in CI.
🐛 Copy/mount fixes: no longer mounts when source and destination credentials differ, and falls back to blob upload when a cross-repo mount fails.
