Update go.mod module declaration, all require lines, and .go import paths from forge.lthn.ai to dappco.re. Dependencies updated: core v0.5.0, log v0.1.0, io v0.2.0. Replace directives added for local module resolution. forge.lthn.ai/core/cli and go-inference retained at old paths (not yet migrated). Co-Authored-By: Virgil <virgil@lethean.io>
