Release 0.2.0

This is the initial tagged release of rucat.

Features

• Multiple Output Formats: Supports ansi, utf8, markdown, ascii, xml, json, and pretty (syntax highlighting) formats.
• Line Numbering: Prepend line numbers to output with the -n/--numbers flag.
• Clipboard Support: Copy output directly to the system clipboard with the -c/--copy flag.
• Flexible Input: Process files, directories, stdin, and NUL-separated file lists from commands like find.
• Path Manipulation: Use --strip to remove leading path components from file headers.
• Configuration: Set default options via a config.toml file in the user's config directory.

Bug Fixes

• Resolved Rust 2024 Edition compatibility lints (ref mut bindings).
• Silenced unavoidable duplicate dependency warnings flagged by clippy::cargo.
• Corrected conditional compilation guards for the clipboard feature to eliminate unused variable warnings.
• Fixed logic in the release workflow to ensure smoke tests run correctly on macOS ARM builds.

Build

• Pinned the Rust toolchain to stable using rust-toolchain.toml for consistent builds.
• Regenerated Cargo.lock to resolve dependency graph corruption.
• Configured cargo deny to allow an unmaintained transitive dependency (yaml-rust) and unavoidable duplicate crate versions.
• Removed invalid .clippy.toml configuration file.

Continuous Integration

• Updated check.sh to accurately simulate the CI environment by isolating CARGO_HOME.
• Ensured all build and test commands in the release workflow consistently use the correct target architecture.
• Standardized shell execution to bash across all operating systems in CI workflows for improved reliability.

Refactor

• Improved function signatures in the main binary to resolve clippy::too_many_arguments and clippy::needless_pass_by_value lints.
