Create IP protection vault prompt system (#108)

Implements a complete vertical slice of the IP Vault feature for
BlackRoad OS, providing cryptographic timestamping and evidence
generation for ideas and intellectual property.

## Components Added

### Agent Layer
- **VaultAgent** (`agents/categories/security/vault_agent.py`):
  - Deterministic text canonicalization
  - Multi-hash generation (SHA-256, SHA-512, Keccak-256)
  - LEO (Ledger Evidence Object) construction
  - Verification text generation
  - Blockchain anchoring preparation

### Backend API
- **Models** (`backend/app/models/leo.py`):
  - LEO: Stores cryptographic hashes and metadata
  - AnchorEvent: Audit trail for blockchain anchoring

- **Schemas** (`backend/app/schemas/leo.py`):
  - LEOCreate, LEOResponse, LEODetail, LEOList
  - AnchorRequest, AnchorEventResponse

- **Router** (`backend/app/routers/ip_vault.py`):
  - POST /api/vault/leos - Create new LEO
  - GET /api/vault/leos - List LEOs (paginated)
  - GET /api/vault/leos/{id} - Get LEO details
  - POST /api/vault/leos/{id}/anchor - Initiate anchoring (stub)
  - GET /api/vault/leos/{id}/events - Get anchor events

### Frontend
- **API Client** (`backend/static/js/api-client.js`):
  - createLEO(), getLEOs(), getLEO()
  - anchorLEO(), getLEOEvents()

- **App** (`backend/static/js/apps.js`):
  - loadIPVault() - Load and display LEOs
  - vaultIdea() - Create new LEO from form
  - viewLEO() - Show detailed LEO modal with verification

- **UI** (`backend/static/index.html`):
  - Desktop icon (🔐 IP Vault)
  - Window with form and list view
  - Start menu integration

## Features

- **Deterministic canonicalization**: Ensures reproducible hashing
- **Multi-hash support**: SHA-256, SHA-512, Keccak-256
(Ethereum-compatible)
- **Verification instructions**: Auto-generated proof-of-authenticity
text
- **Blockchain-ready**: Prepared for Bitcoin, Litecoin, Ethereum
anchoring
- **Clean separation**: Agent logic, API, database, frontend all
decoupled

## Testing

- Python syntax validated for all new files
- JavaScript syntax validated
- VaultAgent tested end-to-end with sample idea
- All hashes computed successfully

## Next Steps

- Implement actual blockchain anchoring
- Add RoadChain integration
- Export LEOs as legal-grade PDFs
- Add user authentication to LEO creation
