v1.1.0

[1.1.0] - 2026-07-29

Added

• Pure string-based conversion API convert_yaml_to_json() / convert_json_to_yaml() in yamlcli_core, usable as a library without touching the filesystem
• py.typed marker so downstream projects can type-check against yamlcli (PEP 561)
• Shared pytest fixtures in tests/conftest.py and golden outputs in tests/expected_outputs.py
• Characterization tests (tests/test_characterization.py), version-resolution tests (tests/test_version.py), and repository-metadata use-case tests (tests/test_usecase_repo_metadata.py)
• CLI tests for JSON decode errors, file removal between existence check and open, and the main() entry point

Changed

• yaml_to_json() / json_to_yaml() are now thin file wrappers that read with explicit UTF-8 encoding and delegate to the new pure conversion functions
• Simplified the --to-json / --to-yaml exclusivity check and merged the YAML/JSON parse-error handlers in the CLI
• get_version() now tolerates missing tomllib on Python < 3.11 and narrows exception handling to OSError / TOMLDecodeError
• Added type annotations and docstrings across cli, yamlcli_core, and helper_func

Fixed

• Moved types-pyyaml from runtime dependencies to the dev dependency group
