Security: suppress unfixable rsa advisory, verify all 2026 CVEs already patched

[Copilot]

Security audit flagged 8 vulnerabilities. 7 are already resolved in Cargo.lock; the remaining one (rsa Marvin Attack) has no upstream patch and needs explicit suppression in both cargo-deny and cargo-audit tooling.

Vulnerability Status

Advisory	Package	Resolution
RUSTSEC-2026-0066	astral-tokio-tar	✅ Lock has 0.6.0 (patched ≥0.6.0)
RUSTSEC-2026-0044/45/46/47/48	aws-lc-sys	✅ Lock has 0.39.0 (patched ≥0.38.0–0.39.0)
RUSTSEC-2026-0049	rustls-webpki	✅ Lock has 0.103.10 (patched ≥0.103.10)
RUSTSEC-2023-0071	rsa	⚠️ No upstream patch — suppressed with justification

Changes

• .cargo/audit.toml (new): Suppresses RUSTSEC-2023-0071 for cargo-audit, matching the existing deny.toml ignore entry. Without this, the scheduled workflow creates a new issue on every run for an advisory with no fix. Justification: rsa enters the graph via recoco-core → sqlx → sqlx-mysql; Thread doesn't use MySQL or expose RSA private-key operations to network timing observation.

Reviewer's Guide

.cargo/audit.toml is added to configure cargo-audit to ignore the known, currently-unfixable RUSTSEC-2023-0071 advisory affecting the rsa crate, with in-file justification documenting why the project is not exploitable and when to re-evaluate.

Pull request overview

Adds repository-level cargo-audit configuration to suppress an unpatchable RustSec advisory (rsa Marvin Attack) so scheduled security scans don’t continuously raise noise, while confirming other flagged advisories are already resolved via Cargo.lock.

Changes:

• Add .cargo/audit.toml with an ignore entry for RUSTSEC-2023-0071 plus rationale (aligning with deny.toml’s existing ignore).
• Document transitive dependency path and re-evaluation guidance for the suppression.
