Supersedes #6335. Built on #6334's head 715bcd4 (entry text states the dev-dependency reality). Fixes the quorum findings: the version pin is now workspace = true; the entry states why env_key stays in aprender-contracts (cannot build-depend or include!() across the package boundary; the test shared_key_crate_agrees_with_env_key_and_the_macro pins the two copies). 302 lines.

§13.11 rung 1 — quorum shadow verdict

S13-SHADOW pr=6348 head=629d12307be1b298a1996f92910318306f1b9a18 verdict=REFUSE class=Q1 arm_rc=1

Shadow mode: this records a verdict and merges nothing. A refusal
to arm is not a block (§13 adds zero rows to §7) — the pull request is
exactly as green as it was.
