chore(io): replace hyper-hickory with slimmer internal version

[tobz]

Summary

PR title says it all, really.

Given the RustSec advisories related to hickory-resolver that we can't resolve until hyper-hickory updates, I opted to replace our usage of hyper-hickory with a slimmed down version. We use a fraction of what hyper-hickory exposes, so this just tightens up our supply chain a wee bit by depending on one less crate while also allowing us to bring in the necessary transitive dependency bumps.

Change Type

• Bug fix
• New feature
• Non-functional (chore, refactoring, docs)
• Performance

How did you test this PR?

Seems like we are still dependent on a vulnerable version of hickory-proto:

147 │ hickory-proto 0.26.1 registry+https://github.com/rust-lang/crates.io-index
    │ ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ security vulnerability detected
    │
    ├ ID: RUSTSEC-2026-0118
    ├ Advisory: https://rustsec.org/advisories/RUSTSEC-2026-0118

Not sure if you expected that to be fixed by this though or just other vulnerabilities.

Explanation

Confidence level: 90.00%
Effect size tolerance: |Δ mean %| ≥ 5.00%

Performance changes are noted in the perf column of each table:

• ✅ = significantly better comparison variant performance
• ❌ = significantly worse comparison variant performance
• ➖ = no significant change in performance

A regression test is an A/B test of target performance in a repeatable rig, where "performance" is measured as "comparison variant minus baseline variant" for an optimization goal (e.g., ingress throughput). Due to intrinsic variability in measuring that goal, we can only estimate its mean value for each experiment; we report uncertainty in that value as a 90.00% confidence interval denoted "Δ mean % CI".

For each experiment, we decide whether a change in performance is a "regression" -- a change worth investigating further -- if all of the following criteria are true:

1. Its estimated |Δ mean %| ≥ 5.00%, indicating the change is big enough to merit a closer look.

2. Its 90.00% confidence interval "Δ mean % CI" does not contain zero, indicating that if our statistical model is accurate, there is at least a 90.00% chance there is a difference in performance between baseline and comparison variants.

3. Its configuration does not mark it "erratic".
