Restore fails on every branch since October 13: NuGet audit flags System.Security.Cryptography.Pkcs 10.0.0 (GHSA-2fmv-rv2c-59x7, GHSA-846f-f764-76mx, both .NET denial of service), and TreatWarningsAsErrors turns the warnings into errors. The package comes in through MailKit's MimeKit 4.18.1, which allows 10.0.0. This references the patched 10.0.13 directly from Exceptionless.Insulation, the project that references MailKit.

Validation: restore and build of Exceptionless.slnx with no warnings; the Web, Job, and Insulation projects resolve 10.0.13; MailerTests (35) pass. Local restore did not reproduce the audit error even with a fresh HTTP cache, so CI confirms the audit result. This unblocks CI and /preview for open PRs such as #2661 and #2634.

🤖 Generated with Claude Code

MimeKit (through MailKit) allows System.Security.Cryptography.Pkcs 10.0.0,
which GHSA-2fmv-rv2c-59x7 and GHSA-846f-f764-76mx (CVE-2026-70162 and
CVE-2026-84008, published October 13) flag. NuGet audit treats those
warnings as errors, so restore fails on every branch. Reference the patched
10.0.13 directly.
