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.

+      The agent-runtimes project repo is cloned at /workspace/project.
+      Change to that directory before doing any work.
+
+      Draft a spec for the following concept and commit it to the repo.
+
+      **Title**: ${item.title}
+
+      ${item.body}
+
+      Steps:
+      1. cd /workspace/project
+      2. Read existing specs in spec/ to understand the format
+      3. Create a slug from the title (lowercase, hyphens instead of spaces)
+      4. Write the spec to spec/<slug>.md following the project spec format
+      5. git add spec/<slug>.md && git commit -m "spec: auto-draft ${item.title}" && git push
+      6. Call task_complete with a one-sentence summary
+
+      The spec should have numbered requirement IDs, clear acceptance criteria,
+      and error handling. Follow the format of existing specs in spec/.
