הורדת ORAS CLI 1.3.4

ORAS CLI v1.3.4 is a security-focused maintenance release. It scopes registry credentials — mTLS client certificates, custom `--header` values, and `--debug` trace output — strictly to the configured registry origin, and adds an opt-in `--force` copy mode for registries that report incomplete content as present.

## Highlights

• 🔒 **Security:** three credential-scoping advisories are fixed — mTLS client certificates ([GHSA-h3wm-jjqf-8jm2](https://github.com/oras-project/oras/security/advisories/GHSA-h3wm-jjqf-8jm2)), custom request headers ([GHSA-whvf-jp7m-59f3](https://github.com/oras-project/oras/security/advisories/GHSA-whvf-jp7m-59f3)), and `--debug` HTTP traces ([GHSA-5jhf-2qmf-m8c5](https://github.com/oras-project/oras/security/advisories/GHSA-5jhf-2qmf-m8c5)). All three were reported by Hardik Mehta ([@hardw00t](https://github.com/hardw00t)).
• ✨ **`oras cp` and `oras push` gain `--force`**, which walks every referenced manifest instead of trusting the destination's `Exists()` response — this fixes `manifest blob unknown` failures against pull-through caches (ACR Artifact Cache, ECR pull-through, GAR remote repositories).
• ⚡ **Shared authentication cache:** repeated in-process calls now reuse credentials instead of re-running the 401 challenge on every call.
• 🛡️ **Supply-chain hardening:** release checksums and archives are now GPG-signed in the release workflow with the ORAS project release key.

## ✨ Features

• Add `--force` to `oras cp`/`oras push` to handle partially-populated destinations by @renshao in #2061
• Save authentication context between calls so in-process usage authenticates once by @TerryHowe in #1923
• Sign release checksums in the release workflow by @TerryHowe in #2112

## 🐛 Bug Fixes

• Avoid send on closed channel in the progress messenger by @harshasiddartha in #2126
• Route logger output to command stderr by @vigneshakaviki in #2123

## 🔒 Security

• **Registry mTLS client certificates are disclosed to cross-origin TLS peers** (CWE-201, [GHSA-h3wm-jjqf-8jm2](https://github.com/oras-project/oras/security/advisories/GHSA-h3wm-jjqf-8jm2))：a certificate supplied via `--cert-file`/`--key-file` was installed on a single shared transport and presented to any HTTPS peer, including cross-origin redirect and bearer-realm targets and HTTPS proxies. The certificate is now scoped to the configured registry origin.
• **Registry custom credentials are forwarded across HTTP origins** ([GHSA-whvf-jp7m-59f3](https://github.com/oras-project/oras/security/advisories/GHSA-whvf-jp7m-59f3))：values passed with `--header`/`--from-header`/`--to-header` were appended to every request, including redirect targets and bearer token realms on other hosts. They are now stripped for any origin that does not match the configured registry.
• **Debug HTTP traces expose replayable bearer credentials** (CWE-532, [GHSA-5jhf-2qmf-m8c5](https://github.com/oras-project/oras/security/advisories/GHSA-5jhf-2qmf-m8c5))：`--debug` trace output persisted URL userinfo and query parameters (e.g. pre-signed `X-Amz-Signature`), `Location`/`Content-Location`/`Referer` headers, cookies, proxy authorization, configured custom headers, and token response bodies. These are now redacted.

All three were reported by Hardik Mehta ([@hardw00t](https://github.com/hardw00t)).
