feat: add list hygiene judge skill

[ArgonautWorks]

What changed

• add the public list-hygiene-judge graph skill
• read and read back contact state through current native data.read_projection
• record only evidence-bound re-permission or hard-bounce suppression transitions through data.append_event with compare-and-set idempotency
• stop without an append for stale/missing evidence, ambiguous recovery, version drift, invalid metrics, or an active unsubscribe marker
• keep all message delivery outside the skill and name a later independent send-as run as the downstream enforcer

Why

List hygiene needs a durable, replay-safe consent decision between engagement evidence and sending. This package uses the current Runx 0.8.2 graph and data-store contracts, including an intentional finalize result producer, portable supervised Node runners, native data operations, and projection readback.

Operator impact

Operators get a sealed decision and readback-bound transition without campaign-send authority. Retries carry the exact idempotency key, concurrent state drift fails closed, and stop paths leave contact state unchanged.

Validation

• runx-cli 0.8.2
• node --check skills/list-hygiene-judge/run.mjs — passed
• runx skill inspect ./skills/list-hygiene-judge --json — ready, fully bound, no unresolved edges
• runx harness ./skills/list-hygiene-judge -R <fresh-dir> --json — 8/8 cases passed, zero assertion errors
• hosted registry publish gate — passed; argonautworks/list-hygiene-judge@0.1.0 published
• digest-pinned clean install and post-install inspect — passed
• post-publish registry dogfood suppression run — sealed after read, append, and readback
• root and complete six-receipt tree verification — production Ed25519 signatures valid, zero findings
