S00-020: Release environment remediation for verified network access

Changes: Release S00-020 external wait through tasks.py after approved HTTPS probes. The local ignored runner configuration now uses automatic approval review with the workspace-write sandbox retained. S00-003 remains blocked until remediation implementation and independent review.
Validation: Official Node v24.21.0 SHASUMS256.txt and npm Stanza registry HEAD requests returned HTTPS 200 through the configured proxy in approved host execution. tasks.py release-external succeeded; runner --dry-run selects S00-020 with configuration_required=false. Pinned runtime execution, locked installation and integrity verification have not been performed.
