Make path-boundary checks separator-agnostic by exposing and enhancing PathMapper.normalizePath and using it in processMonitorDownload. normalizePath now converts backslashes to forward slashes, collapses redundant separators and `..` segments, and strips trailing separators (except root). The relocation test in processMonitorDownload now compares normalized download/save paths and treats a path as "relocated" only when equal-to or a child of the save path (boundary enforced). Added unit and integration tests to cover Windows backslashes, trailing separators, `..` collapse, sibling-prefix edge cases, and preserved existing wait/retry behavior (#209).
Introduces a full notification system with support for Discord and Pushover backends, event triggers, and message formatting. Adds backend services, processors, and API endpoints for managing notifications, as well as a new Notifications tab in the admin settings UI. Updates documentation, database schema, and tests to cover notification features and approval workflow improvements. Also changes project license from MIT to AGPL v3.
Introduced a Vitest-based backend unit testing framework with supporting scripts, helpers, and GitHub Actions integration. Refactored the admin settings page to a modular architecture, splitting monolithic logic into feature-specific tabs and hooks for improved maintainability and testability. Updated documentation to reflect the new testing setup and settings architecture, and added new dependencies for testing utilities.
