Subject: [PATCH] Implement minimal create and extract operations (#35)

* Implement minimal create and extract operations

Adds basic tar archive functionality using tar-rs library with proper
error handling infrastructure.

Core Implementation:
- TarError enum implementing UError for uucore integration
- Extract operation (-x) for unpacking tar archives
- Create operation (-c) for creating tar archives from files/directories
- Verbose mode (-v) for both operations
- Proper CLI argument parsing with -f flag for archive file

Error Handling:
- Comprehensive error types (IoError, InvalidArchive, FileNotFound, etc.)
- Proper error conversion from io::Error
- UError trait implementation for exit code handling

This provides the minimal foundation for tar functionality. Both create
and extract are included together since they depend on each other for
testing purposes.

Includes 18 tests total:
- 8 integration tests (CLI basics, create/extract operations, error handling)
- 10 unit tests (CLI flag parsing, error type handling)
- Unit tests organized in src/uu/tar/tests/ separate from implementation

Note: Run `cargo test --workspace` to execute all tests including unit tests.

* Re-add cognitive complexity warning suppression for uu_app function

* Sort out tar/tarapp conflict

Rename package from "tar" to "tarapp" in Cargo.toml and update
dependencies to use workspace for tar.

* fix(errors): improve error handling and exit codes for tar operations

- Updated error messages for file not found and permission denied cases.
- Fix exit codes for various TarError types to conform to standard.
- Refactored extract_archive to use new error handling.
- Adjusted tests to reflect updated exit codes.

* Update for error changes (fixes cargo test --all)

* Use arg! macro and comment out rather than remove the unimplemented items.

* fix(create): Remove duplicate message for missing files in create_archive
