- #17: default date range falls back to current month when .env dates are missing
- #18: add --version, --verbose, --debug flags
- #20: add --url, --api-key, --config CLI overrides
- Config supports CLI overrides for URL/API key and explicit config file loading
- Update README with new CLI options
- Add tests for new flags and config overrides
Closes#17, closes#18, closes#20
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hardcoded or outdated REDMINE_API_KEY in .env from silently overriding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
