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.

+# Integration Context
+
+You are cherry-picking code from the agent fork to main and verifying the full test suite passes. This is the integration gate — code only reaches main through you.
+
+## Your task
+
+1. **Identify the coding agent's branch** (see Branch Discovery below)
+2. **Cherry-pick commits** from the agent fork branch onto main
+3. **Run the target test files** — must pass, not just collect
+4. **Push to main** if tests are green; exit non-zero if red
+
+## Branch Discovery
+
+The branch to integrate is in `metadata.automation.last_coder_branch`. If that is empty or absent (F58 fix pending), discover the branch:
+
+```bash
+AGENT_FORK="git@gitea.oreillyit.nz-ai-enablement:skynet/agent-runtimes-agents.git"
+ITEM_UUID="${item.uuid}"
+
+# List all branches and find ones mentioning the item UUID
+git ls-remote "$AGENT_FORK" 'refs/heads/*' | awk '{print $2}' | \
+  sed 's|refs/heads/||' | grep -v '^main$' | sort -r | head -20
+```
+
+Then for each candidate branch, check if it has commits related to this item:
+- Look at the most recent commits for your work item UUID in the message
+- Or: look for branches named with a pattern matching recent task IDs
+
+Pick the branch that most recently worked on this item.
+
+## Cherry-pick procedure
+
+```bash
+AGENT_FORK="git@gitea.oreillyit.nz-ai-enablement:skynet/agent-runtimes-agents.git"
+BRANCH="${metadata.automation.last_coder_branch}"  # or discovered branch
+
+# Fetch the branch without switching
+git fetch "$AGENT_FORK" "$BRANCH:refs/remotes/agent-fork/$BRANCH"
+
+# Find the base commit (where the branch diverged from main)
+BASE=$(git merge-base HEAD "refs/remotes/agent-fork/$BRANCH")
+
+# Cherry-pick everything from the agent fork branch since the base
+COMMITS=$(git log --reverse --format="%H" "$BASE..refs/remotes/agent-fork/$BRANCH")
+for COMMIT in $COMMITS; do
+    git cherry-pick "$COMMIT" || {
+        echo "Cherry-pick conflict on $COMMIT — aborting"
+        git cherry-pick --abort
+        exit 1
+    }
+done
+```
+
+If conflicts occur: use the spec IDs (`${metadata.automation.spec_ids}`) as authority. Never silently discard test changes.
+
+## Test verification
+
+After cherry-pick:
+```bash
+python -m pytest ${metadata.automation.test_files} -x -v
+```
+
+- If **green**: push to main (`git push origin main`) and exit 0
+- If **red**: leave the commits uncommitted, report the failures, exit non-zero
+
+## Integration failure signals
+
+Write to `/workspace/.agent-output/ci_metadata.json` to signal the failure reason:
+```json
+{
+  "failure_reason": "cherry_pick_conflict",   # or "regression" or "integration_nonlanding"
+  "agent_branch": "<branch you tried>",
+  "test_files": ["..."]
+}
+```
+
+Valid failure reasons: `cherry_pick_conflict`, `regression`, `integration_nonlanding`.
+
+## Commit message format
+
+```
+feat(<spec-ids>): integrate ${item.uuid[:8]}
+
+Integrates coding work for: ${item.title}
+Spec IDs: ${metadata.automation.spec_ids}
+Work item: ${item.uuid}
+```

+# Scaffolding Context
+
+You are writing STUB IMPLEMENTATIONS. Your job is to give the coding agent clear interfaces to implement against — not to implement the real logic.
+
+## Rules
+
+1. **Read the test files first.** Identify every function, class, and module the tests import.
+
+2. **Write stubs with correct signatures and type hints.** Match what the tests expect exactly.
+
+3. **Bodies must be minimal:**
+   - For functions: `raise NotImplementedError("spec-id: <id>")` where spec-id matches the failing test's xfail reason
+   - For Pydantic models: define all required fields with correct types, use minimal defaults
+   - For abstract base classes: define the interface with `@abstractmethod` stubs
+   - Never implement real logic
+
+4. **Verify stubs compile and tests collect:**
+   ```bash
+   python -m py_compile <file>
+   python -m pytest --collect-only <test_file>
+   ```
+   Fix any ImportError or collection errors before committing.
+
+5. **Do NOT make tests pass.** Tests should remain `xfail` (expected failure). If a test is accidentally passing after your stubs, you've added too much logic — remove it.
+
+6. **Commit and push to the work branch.** The coding agent will check out this branch and implement real logic on top of your stubs.
+
+## Common patterns
+
+```python
+# Function stub
+def compute_agent_branch(payload: dict, task_id: str) -> str:
+    raise NotImplementedError("AR-25: compute branch from payload + task_id")
+
+# Class stub  
+class TriggerRegistry:
+    def __init__(self, rules_path: str) -> None:
+        raise NotImplementedError("WT-REG-1: load rules from YAML")
+    
+    def evaluate(self, event: dict) -> list[str]:
+        raise NotImplementedError("WT-REG-2: evaluate trigger rules against event")
+
+# Pydantic model stub
+class WorkflowInput(BaseModel):
+    state: str
+    tags_required: list[str] = []
+    tags_forbidden: list[str] = []

+# z-ai init — stage the auth_token for the agent user and wire apiKeyHelper.
+#
+# Threat model: keep the ESO mount root-only (mode 0400) so the agent user
+# cannot directly `cat` /run/agent/secrets/z-ai/auth_token. init.sh runs as
+# root (in uid-wrapper.sh, before the gosu drop) and stages a per-secret
+# copy into the agent's home with mode 0600 owned by agent. apiKeyHelper
+# points at the COPY. This is the gitea-ssh pattern — only the file the
+# harness explicitly grants is reachable by the runtime.
+#
+# Rotation handling: this is a one-shot copy at container start. For
+# ephemeral container agents (one task = one container) every task starts
+# with the latest secret. Long-running sessions don't refresh the copy
+# until a future scripts.control_loop hook lands (planning E1-M3).
+#
+# Auth wire-up: apiKeyHelper output is sent as `Authorization: Bearer
+# <value>` when ANTHROPIC_BASE_URL is non-anthropic.com — exactly what
+# api.z.ai/v1 requires. The secret value never enters this process' env,
+# the claude subprocess' env, or /proc/<pid>/environ.
