chore: estate-wide chore + stale-path sweep (2026-04-17)

Part of the estate-wide 2026-04-17 cleanup pass. Commits chore-safe
content only: docs, workflow YAML, gitignore, a2ml migration drift,
editorconfig, ncl. Dependency manifests (Cargo.toml/.lock, package.json,
mix.exs, etc.) and source files intentionally held back so no broken
intermediate states where a .rs commit splits from its Cargo.toml.

Also includes stale-path fixes for four ecosystem moves:
  hypatia       -> verification-ecosystem/hypatia
  echidna       -> verification-ecosystem/echidna
  ephapax       -> developer-ecosystem/nextgen-languages/ephapax
  panic-attacker -> games-ecosystem/panic-attacker

Staged files: 1
Held back (source / dep-manifests): 0
