netpulse release - 0.4.2

Added

• /system/stats Endpoint: New system statistics endpoint with self-healing telemetry for runtime observability.
• Detached Task Supervisor: Background supervisor that monitors detached tasks, triggers incremental log pushes via webhooks, and auto-syncs stale tasks.
• Automated Staging Cleanup: Configurable retention-based cleanup of staging directory files to prevent disk exhaustion.
• Webhook Retry Mechanism: Automatic retry with configurable attempts for webhook delivery failures, improving reliability in unreliable network conditions.
• Asynchronous Audit Log Archiver: MongoDB-backed audit log archiver worker for persistent job history and compliance.
• Kubernetes Deployment: Helm chart and raw K8s manifests for production deployment, including Vault auto-init, Redis operator integration, and multi-replica scaling.

Changed

• Unified Vault image version to 1.21 across Docker Compose and Kubernetes deployments.
• Reorganized deployment structure under deploy/ directory (Helm charts, K8s manifests, scripts).

Fixed

• Fixed scheduler edge cases in batch_node_select capacity validation.
• Added timeout for remote template fetching to prevent hanging on unreachable URLs.
• Fixed supervisor sync bug where registry updates could be lost.
• Fixed _handle_file_transfer() return type annotation (dict → list).
• Extracted and centralized sensitive data masking in logger to prevent credential leakage.
