feat: migrate missing harnesses, templates, and workflows from agent-runtimes

Brings the framework CRS repo up to date with all content that was
living in agent-runtimes (local-dev fallback) but hadn't been promoted.

New composites: feature-delivery-loop, integration-direct, scaffolding-repo,
sonnet-impl-narrow, sonnet-manager, test-writing-repo

New contexts: integration/v1, scaffolding/v1, sonnet-manager/v1, z-ai/v1,
airouter/v1/bin (anthropic-compat-wrapper.sh), cp-harness/v1/init.sh

New task-templates: sonnet-integrator.yaml, workflow/* (17 typed workflow
task templates for the Epic 1 pipeline)

Updated: agent-repo/v1/finalize.sh — adds AR-38/F97 empty-deliverable audit
(SKIP_BRANCH_PUSH support, boilerplate-path filtering, ci_metadata.json flag)

Also adds MEMORY.md index and memory/ topic files for the framework repo.

+      You are writing pytest tests for the following task.
+
+      Work item UUID: ${item.uuid}
+      Spec IDs: ${metadata.automation.spec_ids}
+      Expected test files: ${metadata.automation.test_files}
+      Task description: ${item.body}
+
+      Rules:
+      - Write tests to exactly the files listed in test_files (create if missing, append if existing)
+      - Mark EVERY test @pytest.mark.xfail(strict=True, reason="<spec-id>: <description>")
+      - Tests must FAIL when the implementation does not exist yet
+      - Write minimal import stubs if needed to prevent ImportError — no real logic
+      - Run: python -m pytest --collect-only <test_file> to verify collection before committing
+      - Commit and push to the work branch
+
+      After writing tests, run the specified test files to confirm they are collected
+      and fail appropriately (xfail with strict=True).
