feat(viking): add local server management for privacy-first deployment
- Add viking_server.rs (Rust) for managing local OpenViking server process - Add viking-server-manager.ts (TypeScript) for server control from UI - Update VikingAdapter to support 'local' mode with auto-start capability - Update documentation for local deployment mode Key features: - Auto-start local server when needed - All data stays in ~/.openviking/ (privacy-first) - Server listens only on 127.0.0.1 - Graceful fallback to remote/localStorage modes Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* Viking Adapter - ZCLAW ↔ OpenViking Integration Layer
|
||||
*
|
||||
* Maps ZCLAW agent concepts (memories, identity, skills) to OpenViking's
|
||||
* viking:// URI namespace. Provides high-level operations for:
|
||||
* - User memory management (preferences, facts, history)
|
||||
* - Agent memory management (lessons, patterns, tool tips)
|
||||
* - L0/L1/L2 layered context building (token-efficient)
|
||||
* - Session memory extraction (auto-learning)
|
||||
* - Identity file synchronization
|
||||
* - Retrieval trace capture (debuggability)
|
||||
*
|
||||
* Supports three modes:
|
||||
* - local: Manages a local OpenViking server (privacy-first, data stays local)
|
||||
* - sidecar: Uses OpenViking CLI via Tauri commands (direct CLI integration)
|
||||
* - remote: Uses OpenViking HTTP Server (connects to external server)
|
||||
*
|
||||
* For privacy-conscious users, use 'local' mode which ensures all data
|
||||
* stays on the local machine in ~/.openviking/

* // Check server status

* const status = await manager.getStatus();
|
