8 known dependency vulnerabilities including 3 HIGH severity

[brandonrc]

Problem

cargo audit reports 8 advisories, 3 at HIGH severity:

Crate	Version	Issue	Severity
aws-lc-sys	0.37.1	PKCS7 signature bypass	HIGH
aws-lc-sys	0.37.1	CRL bypass	HIGH
aws-lc-sys	0.37.1	3 additional advisories	MEDIUM
quinn-proto		DoS vulnerability (CVSS 8.7)	HIGH
time		Stack exhaustion	MEDIUM
rustls-webpki		CRL matching issue	MEDIUM

Suggested Fix

1. cargo update to pull latest compatible versions
2. Bump aws-lc-sys to >= 0.39.0 (may require updating aws-sdk-* crates)
3. Verify quinn-proto update resolves the DoS advisory
4. Run cargo audit to confirm zero HIGH advisories remain
