v1.0.3

Added

• cortex update self-update command: downloads latest release from GitHub, verifies SHA-256 checksum, replaces binary (with Windows rename-then-replace pattern), and triggers reindex
• cortex reindex command: deletes and rebuilds the graph database from scratch
• Default exclusions for .serena, .cursor, .kiro, .agent directories and lock files (pnpm-lock.yaml, package-lock.json, yarn.lock, Cargo.lock)
• Renamed .cortex-ignore to .cortexignore for consistency
• Installer PATH configuration (Windows setx, Unix shell profile export)
• Post-install automatic reindex with 120s timeout
• Windows x86 (win32-ia32) binary support in release workflow and npm installer

Changed

• Unified UI fully dark-themed (#1e1e2e background) with corner-positioned icon navigation replacing the nav bar
• Hotspots table uses overflow-x: auto to prevent horizontal overflow
• Statistics overlay uses CSS Grid with tabular-nums for numeric alignment
