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.

+# Token Gotchas
+
+## `~/.config/agent-runtimes/tokens.json` uses flat structure
+
+Symptom: code expecting a nested `{provider: {access_token, expires_at}}` shape fails to find the token.
+
+Fix: the file is flat — `{"access_token": "...", "expires_at": <unix_seconds>}`. There is no provider key. Read it as a flat dict. When debugging "is my token expired?", compare `expires_at` against `int(time.time())` directly — both are Unix epoch seconds.
