Merged github/main into dev to resolve PR #2 conflict. Took github/main
code for all conflicted files (new features: signal, wait, start/run API,
UI streaming, process_global). Resolved go.mod by keeping dappco.re module
paths and using api v0.2.0 (dappco.re-compatible). go mod tidy confirms clean.
