migrate cc-config to chezmoi: add all skills, agents, and openclaw installer

- Add 4 missing skills: chromedp-alpine-container, claude-memory-api,
  openclaw-custom-model-provider, webrtc-turn-shared-secret
- Add 9 custom agents: sre, dba, devops-engineer, platform-engineer,
  security-engineer, network-engineer, observability-engineer,
  home-automation-engineer, cluster-health-checker
- Add openclaw-install.sh: standalone script to clone dotfiles and
  install skills/agents/hooks/settings to OpenClaw's home directory
  Replaces the cc-config NFS volume + sync.sh approach

+description: Store and recall persistent memories using the memory-tool CLI. Use when the user asks to remember something, recall a previous memory, or when you want to persist knowledge across sessions.
+---
+
+# Claude Memory API
+
+You have access to a persistent memory system via the `memory-tool` CLI command.
+
+## When to Use
+
+- User says "remember this", "save this", "note that..."
+- User asks "do you remember...", "what do you know about...", "recall..."
+- You discover important facts worth persisting (user preferences, project patterns, debugging insights)
+- You need to check if you already know something before asking the user
+
+## Commands
+
+### Store a memory
+```bash
+memory-tool store "content to remember" --category <category> --tags "tag1,tag2"
+```
+Categories: `facts`, `preferences`, `patterns`, `debugging`, `architecture`
+
+### Recall memories (semantic search)
+```bash
+memory-tool recall "search query"
+```
+
+### List all memories
+```bash
+memory-tool list
+memory-tool list --category facts
+```
+
+### Delete a memory
+```bash
+memory-tool delete <memory-id>
+```
+
+## Guidelines
+
+- Always `recall` before storing to avoid duplicates
+- Use specific, descriptive content — memories should be self-contained
+- Choose the most relevant category
+- Add tags for better recall later
+- When the user says "remember X", store it immediately and confirm
