v0.1.21

Re-grounds the plugin on the live Similarweb MCP surface, which grew from 80 tools to 113 and renamed 8 of them into a get-website-analysis-* namespace.

Fixed

• sw-channel-mix aborted on every run. Its required probe tool read as absent under the new names, and that tool's pinned absence outcome is ABORT.
• sw-competitive-teardown silently dropped its channel breakdown and PPC investment sections.
• sw-aeo-audit's AI-referral fallback called a tool that no longer exists.
• The Cowork teardown artifact failed on page load.
• 403 claims detection was silently broken. The server's 403 message changed wording and the "missing the required claims" phrase moved into the actions array, so message-gated detection would miss a real claims gap. Detection now keys on HTTP 403 plus error.code FORBIDDEN_ERROR only.

Added

• AI-referral measurement via the Gen AI traffic channel. get-website-analysis-traffic-channels now returns a ten-channel taxonomy including Gen AI with absolute visits at 10 credits per month, so sw-aeo-audit leads with it and costs less than the proxy it replaces. Naming the individual AI sources stays opt-in.
• Rename-transition safety. If a documented tool is absent but its retired predecessor is live, the plugin calls the predecessor and says so. Connectors do not all update together.
• A tool-name drift guard in build.py --validate, so the next rename wave fails the build instead of shipping. It scans every file type across the shipped trees, the generated mirrors, and the root docs.
