Pull request overview

This PR adds several significant features to the logwatcher tool including exclude patterns for filtering out unwanted log lines, shell completion generation support, Docker containerization, and security improvements with ReDoS protection. The version is also updated from 0.1.0 to 0.2.0 with the version string now correctly sourced from Cargo.toml.

Key changes:

• Added exclude pattern functionality (--exclude/-e) with support for both literal and regex matching
• Implemented shell completion generation for bash, zsh, fish, and PowerShell via --completions flag
• Added Docker support with multi-stage Dockerfile for containerized deployment
• Enhanced security with ReDoS protection using regex size limits
• Fixed version reporting to use env!("CARGO_PKG_VERSION") instead of hardcoded value
