chore: add go.work

[doringeman]

• Added a go.work for model-runner and model-runner/cmd/cli. Ref: https://go.dev/doc/tutorial/workspaces.
• Fixed the validate-tests target.
• Added a new step in the CI workflow to check that go mod tidy and go work sync are run.

This PR should help with the errors in #194 and also ease the importing (using of) github.com/docker/model-runner in github.com/docker/model-runner/cmd/cli (model-cli).

Summary by Sourcery

Add go.work workspace and switch CLI to use local module while upgrading dependencies and test tooling

Enhancements:

• Refactor CLI imports to use local model-runner/pkg/distribution paths instead of external model-distribution module
• Upgrade a variety of dependencies in the root and CLI modules including containerd, ghw, Prometheus, OpenTelemetry, go-ole, gogo/protobuf, and more
• Modify the CLI Dockerfile to run unit tests within the cmd/cli directory
• Adjust docker-bake configuration to specify the Dockerfile for the validate-tests target

Chores:

• Add go.work and go.work.sum to manage the repository as a Go workspace
• Add replace directive for the local model-runner module in cmd/cli/go.mod and remove the legacy model-distribution requirement

Summary by Sourcery

Add Go workspace support, refactor CLI to use local module, bump dependencies, and enforce module hygiene in CI

Enhancements:

• Update various dependencies in root and CLI modules to latest patch versions
• Refactor CLI commands to import distribution packages from local model-runner module

Build:

• Modify CLI Dockerfile to run unit tests within the cmd/cli directory

CI:

• Add CI step to run go mod tidy, go work sync, and verify no mod file diffs

Chores:

• Add go.work and go.work.sum for Go workspace setup and add local replace directive in cmd/cli/go.mod
• Fix validate-tests target by specifying the correct Dockerfile in docker-bake.hcl

Reviewer's Guide

Introduces a Go workspace for multi-module management, upgrades core dependencies, refactors the CLI to use the local model-runner module, and strengthens CI/build configurations to enforce module hygiene and correct test execution.
