chore(ci): ignore RUSTSEC-2026-0173 proc-macro-error2 advisory

[risu729]

Summary

• Ignore new RUSTSEC-2026-0173 advisory for unmaintained proc-macro-error2
• Fixes cargo deny check failures in CI (lint job)

proc-macro-error2 is a transitive dependency via age, mlua (vfox), tabled, and rops. There is no safe upgrade path yet; this mirrors the existing ignore for the original proc-macro-error advisory (RUSTSEC-2024-0370).

Test plan

• CI lint job passes (cargo deny check)

Poem

A bunny hops through config files with care,
Finding advisories that linger in the air,
One more suppressed—RUSTSEC-2026—so fair,
The dependency tree stays safe with reason to spare! 🐰

Greptile Summary

Suppresses the new RUSTSEC-2026-0173 advisory for the unmaintained proc-macro-error2 crate in cargo deny to unblock CI, mirroring the existing ignore for the original proc-macro-error advisory (RUSTSEC-2024-0370).

• Adds one entry to the [advisories].ignore list in deny.toml with a clear reason string that names the affected transitive dependents (age, mlua, tabled, rops) and notes no safe upgrade path yet.

Confidence Score: 5/5

Safe to merge — single-line addition to a CI advisory suppresslist with no runtime impact.

The change touches only deny.toml, adding one structured ignore entry that follows the exact same format as the other entries in the file. The reason string accurately names the affected transitive crates and states there is no upgrade path, consistent with the project's established practice for unmaintained dependency advisories.

No files require special attention.
