[WIP] Add GOPHER harness functionality for precision execution

[Copilot]

• Create go.mod for module github.com/verbatimt/gopher
• Implement pkg/inference — Inferencer interface, Step & Plan types
• Implement pkg/execution — Executor interface, Result type, local executor
• Implement pkg/accumulator — recursive accumulator that prevents drift
• Implement pkg/harness — event-driven orchestrator wiring inference ↔ execution
• Implement cmd/gopher/main.go — CLI entry point
• Add unit tests for each package
• Update README with system description
• Run validation (parallel_validation)

Original prompt

GOPHER

Granular Orchestration Protocol Harness & Execution Runner

"I don't think. I just do."

GOPHER is a distributed, event-driven agentic harness designed for high-precision, deterministic, autonomy. It decouples the Inference (the brain) from the Execution (the muscle) using restricted zero-shot microstep linear execution path with a recursive accumulator that prevents agentic drift and hallucination.
