v1.2 — Offline sideload path

Adds an offline sideload path for tenants where outbound GitHub access is blocked by Cowork's egress policy.

Distribution PDF

• claude-cowork-asksage-quickstart-v1.2.pdf — 9-page printable quickstart covering inference setup, plugin install, and the new offline sideload path.

New

• Part 3 of the README — "Offline sideload (when egress is blocked)". Full procedure for downloading the plugin repo on an unrestricted machine, transferring to the target workstation, extracting to C:\Program Files\Claude\org-plugins, and registering as a local marketplace.
• scripts/sideload-plugins.ps1 — elevated PowerShell helper automating extraction, flattening, and marketplace registration.
• New egress-troubleshooting section in plugins.md with three remediation paths.
• Three new rows in the README troubleshooting table for egress errors and sideload edge cases.

Background
The upstream anthropics/knowledge-work-plugins marketplace lists ~41 plugins. Roughly 20 are bundled in the repo (source: "./folder") and install fully offline from a local sideload — including all 11 on our recommended list. The remaining ~21 are partner-built with external GitHub URL sources; those still require egress to install. The sideload path covers every plugin that matters for the quickstart.

Unchanged

• claude_desktop_config.json — no config changes needed for sideload.
