S00-026: Verify pinned Linux runtime and isolated locked dependency access

Changes: Add a bounded reproducible HTTPS/checksum/runtime probe under environment-access, vendor checksums, unchanged parent manifest/lock copies, strict npm settings, result and reproduction notes. Record evidence and QA handoff; submit S00-026 without completing parent tasks.
Validation: Run verify.py twice successfully: vendor Linux archive SHA256 matched, Node 24.21.0/npm 11.19.0 executed, fresh-cache npm ci installed eight integrity-locked packages with scripts disabled, parent bytes stayed unchanged and Stanza import passed. tasks.py validate, git diff --check and scoped file whitespace checks passed. No browser/WSS, detached signature or provenance audit performed.
