move pi-mono into companion-cloud as apps/companion-os

- Copy all pi-mono source into apps/companion-os/
- Update Dockerfile to COPY pre-built binary instead of downloading from GitHub Releases
- Update deploy-staging.yml to build pi from source (bun compile) before Docker build
- Add apps/companion-os/** to path triggers
- No more cross-repo dispatch needed

+# Memory Search
+
+Use this skill to find information stored in pi-memory-md memory files.
+
+## Search Types
+
+### Search by Content
+
+Search within markdown content:
+
+```
+memory_search(query="typescript", searchIn="content")
+```
+
+Returns matching files with content excerpts.
+
+### Search by Tags
+
+Find files with specific tags:
+
+```
+memory_search(query="user", searchIn="tags")
+```
+
+Best for finding files by category or topic.
+
+### Search by Description
+
+Find files by their frontmatter description:
+
+```
+memory_search(query="identity", searchIn="description")
+```
+
+Best for discovering files by purpose.
+
+## Common Search Patterns
+
+| Goal             | Command                                                       |
+| ---------------- | ------------------------------------------------------------- |
+| User preferences | `memory_search(query="user", searchIn="tags")`                |
+| Project info     | `memory_search(query="architecture", searchIn="description")` |
+| Code style       | `memory_search(query="typescript", searchIn="content")`       |
+| Reference docs   | `memory_search(query="reference", searchIn="tags")`           |
+
+## Search Tips
+
+- **Case insensitive**: `typescript` and `TYPESCRIPT` work the same
+- **Partial matches**: `auth` matches "auth", "authentication", "author"
+- **Be specific**: "JWT token validation" > "token"
+- **Try different types**: If content search fails, try tags or description
+
+## When Results Are Empty
+
+1. Check query spelling
+2. Try different `searchIn` type
+3. List all files: `memory_list()`
+4. Sync repository: `memory_sync(action="pull")`
