Summary

This PR adds a root repository Taskfile.yml for common local workflows, so contributors can build, test, verify dependencies, and run focused test commands through a single discoverable entrypoint.

Highlights

Repository task entrypoint

• Add a root Taskfile.yml with direct, thin wrappers around the repository's existing dotnet, Python, and DocFX commands.
• Add first-class tasks for restore, clean, build, test, format, deps, docs, and verify.
• Add targeted test tasks for core, governance, governance Redis, smoke tests, and a parameterized test:project workflow for focused test runs.

Repo-facing documentation

• Document the task entrypoint in the root README.md.
• Add the same local workflow guidance to Docs/Home.md so the task layer is visible from the documentation surface as well.
• Keep the task names short and explicit so the command surface stays easy to discover from the repository root.

Build workflow hardening

• Exclude generated obj/**/*.cs and bin/**/*.cs sources from src/ModularityKit.Mutator.csproj.
• Fix duplicate assembly attribute failures that were surfacing during normal repository builds.
• Keep the task definitions thin by fixing the underlying build input issue rather than adding special handling in the task layer.

Why

Issue #49 is about reducing command drift in a repository that already has several build, test, docs, and validation workflows. Contributors should not need to memorize long solution paths and repeated dotnet invocations for common tasks.

This PR adds the root task entrypoint while keeping the implementation low ceremony and aligned with the commands the repository already uses in README guidance and CI.
