Change load_dotenv() to load_dotenv(override=False) so real environment
variables always take priority over stale .env files. This prevents a
hardcoded or outdated REDMINE_API_KEY in .env from silently overriding
a fresh token exported in the shell (#15).
Add .strip() to get_redmine_password() for consistency with all other
config getters — trailing whitespace in .env no longer causes silent
auth failures (#35).
Closes#15, closes#35
Add missing __init__.py to formatters/ so setuptools.find_packages
includes the subpackage in wheel/sdist builds (#16).
Move ODTFormatter import from top-level to lazy import inside
get_formatter_by_extension() so missing odfpy no longer crashes module
load before main() runs. Remove dead except ImportError handler in
cli.py save() block; surface a clear 'odfpy is not installed' message
when the formatter factory returns None for .odt (#25).
Closes#16, closes#25
