v0.3.0: TUI Dashboard and Universal Installer

[0.3.0] - 2026-04-25

Added

• Interactive TUI: Introduced a terminal-based dashboard using ratatui for side-by-side code and security analysis.
• Remote Auditing: Support for fetching and scanning scripts directly from Raw URLs (GitHub/Gists) without writing to disk (memory-only analysis).
• Universal Shell Support: Added native hooks for Bash and Fish, ensuring parity with the existing Zsh integration.
• Mend-Style Automated Installer: A new install.sh that handles dependency checks, compilation, and automatic shell hook injection.
• Final Verdict Logic: Added a summary message providing a clear recommendation (Safe/Caution/Dangerous) based on audit results.
• Word Boundary Detection: Implemented \b regex boundaries to significantly reduce false positives in benign scripts (e.g., encode vs nc).

Changed

• Engine Pivot: Transitioned from a Landlock-based "Enforcement" model to a Static Analysis "Intelligence" model for better portability.
• Global Deployment: The installer now deploys Oversight to ~/.local/bin, moving it out of the development directory for system-wide use.
• Wrapper Logic: Unified the shell logic to focus on a thin "glue" layer, moving the intelligence into the core Rust binary.

Fixed

• Pattern Noise: Fixed an issue where variable names containing command fragments (like 'nc') triggered high-severity network warnings.
• Resource Cleanup: All remote audits are now performed in volatile memory, ensuring no temporary files or sensitive data are left behind.
