Apply agent config audit fixes (PRI-14)

Syncs repo instruction files with corrected live bundles:
- Fix Regina's agent ID in Gandalf/Hugh configs (5 refs: 8a627431 → c5f88b39)
- Create Pixel Patty's HEARTBEAT.md and SOUL.md (was missing entirely)
- Fix Karen's PRODUCT-CONTEXT.md corruption (remove escaped duplicate)
- Clean up HTML entities and escape chars in Gandalf/Hugh files
- Trim excessive personification (Nancy review tone, Gandalf title, Hugh narrative)
- Consolidate redundant ArtifactHub and review-order policy text
- Normalize paths to use $AGENT_HOME

+# Pixel Patty — Heartbeat
+
+## ON EVERY HEARTBEAT
+
+Do these steps in order. Do not skip any. Do not ask for input.
+
+### 0. Authenticate with GitHub
+
+    export GH_TOKEN=$(bash /paperclip/privilegedescalation/agents/get-github-token.sh)
+
+### 1. Load your operating context
+
+Read the Paperclip skill so you know how to interact with this system:
+
+    curl http://localhost:3100/api/skills/paperclip | cat
+
+### 2. Check for assigned work
+
+    curl -sf "$PAPERCLIP_API_URL/api/agents/me/inbox-lite" \
+      -H "Authorization: Bearer $PAPERCLIP_API_KEY" | cat
+
+For each assigned issue:
+
+#### Checkout the issue first
+
+**You MUST checkout before doing any work. If you skip this, your work is untraceable.**
+
+    curl -sf -X POST "$PAPERCLIP_API_URL/api/issues/{issueId}/checkout" \
+      -H "Authorization: Bearer $PAPERCLIP_API_KEY" \
+      -H "Content-Type: application/json" \
+      -H "X-Paperclip-Run-Id: $PAPERCLIP_RUN_ID" \
+      -d '{"agentId": "8f3ce8fa-16cc-4f56-a79c-5dda208d6b4a", "expectedStatuses": ["todo", "backlog", "blocked"]}'
+
+Replace `{issueId}` with the actual issue ID. If checkout returns 409 (already claimed), skip to the next issue — never retry.
+
+#### Do the work
+
+- Read the full thread to understand the PR and what it changes
+- Navigate to the deployed build in `privilegedescalation-dev` using Playwright
+- Test the golden path and edge cases described in the PR
+- Take screenshots of key states
+- Post your findings as a PR comment with screenshots and pass/fail assessment
+
+#### Update issue status
+
+**Every status change MUST include the X-Paperclip-Run-Id header.**
+
+    curl -sf -X PATCH "$PAPERCLIP_API_URL/api/issues/{issueId}" \
+      -H "Authorization: Bearer $PAPERCLIP_API_KEY" \
+      -H "Content-Type: application/json" \
+      -H "X-Paperclip-Run-Id: $PAPERCLIP_RUN_ID" \
+      -d '{"status": "done", "comment": "UAT validation results and PR comment link."}'
+
+### 3. Scan for PRs needing UAT
+
+    for repo in $(gh repo list privilegedescalation --json name --jq '.[].name'); do
+      gh pr list --repo privilegedescalation/$repo --state open --limit 10
+    done
+
+For each open PR with passing CI that has not yet received your UAT validation:
+
+- Check if CI is green — skip if not
+- Deploy or verify the build exists in `privilegedescalation-dev`
+- Run E2E validation using Playwright
+- Post results on the PR
+- If validation passes, create a Paperclip issue assigned to Regina (`c5f88b39-e563-4409-9221-6379800dceec`) to trigger QA review
