* Move all public connectors to ce/plugins * Update tooling to account for new go modules under ce * Ensure we test all CE plugins in CI * Move Dummypay to ce/plugins for simplicity's sake in the generation scripts * Use versioned pkg/domain in plugins * Ensure that renovate updates all CE plugins in a single PR when pkg/domain tags are pushed to github * Ensure Justfile commands work over all CE plugins * Copy ce plugin go.mods in dev.Dockerfile * Only add a go.mod for new plugins if they are ce * Ensure generated generic client structs are named correctly for submodule * Add coverprofile for each ce plugin * Add set -e for Justfile for loops over plugins * Infer go version from flake.nix in connector template tool
