+Enforced Conventional Commits using Husky.NET + CommitLint.Net via the repository-local .NET tool manifest (`dotnet-tools.json`). Key deliverables:
+
+- `commit-message-config.json` — Conventional Commits rules with allowed types
+- `.husky/commit-msg` + `.husky/task-runner.json` — local git hook that blocks non-conforming messages at commit time
+- `.github/workflows/commit-message.yml` — CI mirror that validates the latest commit message using the same config, catching any hook bypasses
+- `CONTRIBUTING.md` updated — single bootstrap (`dotnet tool restore` + `dotnet husky install`) activates all local tools and hooks after cloning

+Delivered `.coderabbit.yaml` at the repo root with:
+
+- `auto_review.enabled: true` + `high_level_summary: true` — automatic PR summary comment on every PR (AC #1)
+- `profile: "chill"` — non-blocking review style that complements rather than replaces human review
+- `auto_apply_labels: true` — automatic PR labelling
+
+AC #3 (OSS licensing) is satisfied — CodeRabbit is free for public repos.
+AC #2 (project conventions awareness) was intentionally skipped by the team; the tool autodiscovers `AGENTS.md` but no explicit `reviews.instructions` were added.

 <!-- SECTION:NOTES:BEGIN -->
 `commit-message.include: "scope"` in Dependabot produces `chore(deps):` or `chore(deps-dev):` based on the dependency type — it does NOT use the ecosystem name as the scope. To get `chore(nuget):` and `chore(github-actions):`, the scope must be baked directly into the `prefix` value and `include: "scope"` must be omitted.

+<!-- SECTION:FINAL_SUMMARY:BEGIN -->
+Updated `.github/dependabot.yml` to add `commit-message` configuration to both ecosystem entries:
+
+- NuGet entry: `prefix: "chore(nuget)"` → produces `chore(nuget): bump <package> from X to Y`
+- GitHub Actions entry: `prefix: "chore(github-actions)"` → produces `chore(github-actions): bump <action> from X to Y`
+
+`include: "scope"` was intentionally omitted — that option produces `deps`/`deps-dev` as scope (dependency-type based), not the ecosystem name. Embedding the scope in `prefix` is the only way to get ecosystem-specific scopes that satisfy the commit-message CI workflow introduced in TASK-3.

+Updated `.github/workflows/test-mutations.yml` to replace the two-step "install stryker.net" block (`dotnet new tool-manifest` + `dotnet tool install --local dotnet-stryker`) with a single `dotnet tool restore` step. This restores all three tools declared in the repo-level manifest (Husky, CommitLint.Net, dotnet-stryker) in one consistent step, matching the bootstrap sequence documented in `CONTRIBUTING.md`. The mutation-testing invocation step (`dotnet tool run dotnet-stryker`) was left unchanged.
