Bump the transitive h2 dependency from 0.4.15 to 0.4.16 to close RUSTSEC-2026-0258 (h2 arbitrary-length HTTP/2 sequence-header DoS). Only the locked version and its checksum change; the dependency graph and all source files are untouched, so this is independent of any feature work. Test: cargo check --jobs 4 --workspace && cargo tree -i h2 (expected 0.4.16) AI: lightly tested

Motivation / Impact
RUSTSEC-2026-0258 is a security advisory affecting
h20.4.15. Upgrading to 0.4.16 (same major 0.4.x line) closes the advisory with a low-risk, lockfile-only change.Verification
h2bump stays within the existing 0.4.x major version, so it is a low-risk lockfile change.cargo check --workspace,cargo deny/ license + advisory checks).Reviewer Notes
No UI change, so no before/after screenshots are attached.
