feat(templates): sync 4 workflow templates from agent-runtimes

Add direct-impl-sonnet@1, plan-review-loop@1, spec-review-loop@1,
test-write-review-loop@1 — present in agent-runtimes but missing here.
These are needed before agent-runtimes drops its baked-in copies and the
CP loads workflow templates exclusively from this CRS repo.

+description: |
+  Direct Sonnet implementation for items with a well-defined scope that skip
+  the spec/test/scaffold pipeline. The item description IS the spec; the agent
+  implements all scope items, runs the project build to verify, and commits.
+  Use for design-coherence, refactoring, or clearly-scoped multi-file tasks.

+      Implement the scope described in this work item. The description lists
+      exactly what needs to be done — treat it as the authoritative spec.
+
+      Work item title: ${item.title}
+      Work item UUID: ${item.uuid}
+
+      Steps:
+      1. Read the work item description carefully — each numbered point is a
+         required change.
+      2. Implement every change in the repository. For dashboard changes, run
+         `cd dashboard && npm run build` after each logical group to verify.
+      3. Fix any build or lint errors before moving on.
+      4. When all changes are in place and the build is green, commit everything
+         with a clear message referencing the work item title.
+
+      Do not skip items. Do not add unrelated changes. Commit only when the
+      build is clean.
