Summary

The eMudhra intermediate CA was compromised, and the roots "emSign ECC Root CA - G3" and "AAA Certificate Services" must no longer be trusted. More Info: https://emudhra.we-have-a-problem.com/

The runtime image gcr.io/distroless/static-debian12:debug still ships both in its CA bundle, so every api-syncagent image up to and including v0.7.0 trusts them.
static-debian13:debug no longer contains them, so this PR switches the runtime base.

The images are also built with Go 1.26.4, which is affected by CVE-2026-111943 (fixed in Go 1.26.10).

This PR bumps Go to 1.26.10 like in kcp itself.

While at it, this PR also bumps dependencies with known vulnerabilities flagged by govulncheck:

• cel-go
• x/net
• otel
• etcd-client
• grpc

Release Notes

Switch the runtime image to distroless static-debian13 to remove the "emSign ECC Root CA - G3" and "AAA Certificate Services" roots following the eMudhra CA compromise, build with Go 1.26.10 to fix CVE-2026-111943, and update golang.org/x/net, grpc, OpenTelemetry, cel-go and etcd client dependencies to fix known vulnerabilities.

Hi @Perseus985. Thanks for your PR.

I'm waiting for a kcp-dev member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.
