S00-026: Record newly available external input for independent verification

Changes: Release external waiting state for S00-026 through tasks.py. Input: Approved external artifact preparation completed through configured HTTPS proxy with TLS verification, without changing system tools or project sources. Authentic local supply: /tmp/luma-approved-toolchain/SHASUMS256.txt, node-v24.21.0-linux-x64.tar.xz, npm-11.19.0.tgz; provenance and SHA256/SRI in /tmp/luma-approved-toolchain/verification.json. Exact Node v24.21.0/npm 11.19.0 execute. Unchanged copied parent lock installed with npm ci --ignore-scripts --engine-strict and Stanza 12.22.1, exit 0; /tmp/luma-approved-toolchain/dependency-verification.json and npm-ci.log. Cache /tmp/luma-approved-toolchain/npm-cache permits fresh offline npm ci without proxy access. Fresh executor must independently verify supplied archives/checksums and repeat installation inside its environment-access scope; no task acceptance claimed.
Validation: External input availability checked; tasks.py release-external succeeded. Acceptance and dependent tasks remain unverified pending fresh executor and independent review.
