WRG 742395bca7 fix(scripts): confine plan-canvas artifact assets and escape 404 paths
Serve artifact pages with a sandbox-only CSP mirroring the viewer iframe, fail-closed realpath confinement for sibling assets, and escape the artifact path in the missing-artifact 404. TDD: 4 RED failures (CSP header, 404 escaping, symlink escape) before the fix, 31/31 GREEN after; markdown/sessions/hook suites and ESLint clean.
