Fix 6 failing tests caused by intentional source changes that landed
without updating dependent test assertions:
- Core test-project: taskPrefix default changed from "FN" to undefined
(commit 800f845e1, derived from project name at runtime)
- Dashboard ScriptsModal.css: replace banned --text-primary with --text
- CLI package-config: update expected pi dep version ^0.79.1 -> ^0.79.9
- CLI skill-sync: document 4 new engine tools in engine-tools.md
- CLI version: update expected release:version script to include
run-ci-distill.mjs
- CLI bundled-plugin-freshness: rebuild stale dist directories
