Decomplect the half-finished fork so the dependency graph has ONE source with no posthog package identity, living under github.com/hanzoinsights. LAYER 1 (package identity): rename straggler package.json names — @posthog/next->@hanzo/insights-next (Next.js SDK; distinct from the existing @hanzo/insights-nextjs config helper), @posthog/mcp->@hanzo/insights-mcp, @posthog/plugin-utils->@hanzo/insights-plugin-utils, @posthog/react-slim->@hanzo/react-slim, @posthog-tooling/release-> @hanzo/insights-tooling-release, and the @posthog/rrweb* family->@hanzo/rrweb* (matching the already-published @hanzo/rrweb*@0.0.47 + minimumReleaseAgeExclude). Repoint every repository.url/homepage/bugs to github.com/hanzoinsights/insights-js and rebrand the PostHog author/description identity to Hanzo AI. LAYER 2 (cross-package imports): rewrite every internal @posthog/* import to its @hanzo/insights*|@hanzo/rrweb* equivalent and the bare module specifiers posthog-js->@hanzo/insights, posthog-node->@hanzo/insights-node, mirrored in package.json deps + the pnpm-lock importer keys. Result: 0 @posthog/* specifiers in packages/tooling/examples/playground source. LAYER 4 (wire protocol) PRESERVED: window.posthog global, ph_* keys, $-prefixed event names, distinct_id, /decide, /e/, /flags, and the __PosthogExtensions__ hook are left unchanged — the Insights server expects them. Also repair pre-existing fork merge damage that blocked compilation (unrelated to naming; identical to origin/main): restore the @hanzo/insights-core ./process subpath (spawn-local/utils, re-matching the published artifact), the lost constructor/var declarations in core + node clients, the mangled external-scripts-loader, the missing TreeShakeable/isPlainError imports, the DeviceId enum member, and stale ../posthog-core-stateless module paths. 26/34 turbo build tasks now pass; remaining failures (browser/react-native and their dependents) are pre-existing fork damage, not rebrand-caused.
