task: prettier tree visualization and flag ordering fixes

- Implement box-drawing characters (├──, └──, │) for
task tree visualization - Fix 'task create' flag ordering by using
[options] in docopt (same as 'task list') - Document TASK_TEST_MODE
environment variable in AGENTS.md Testing section - Add test case for
multi-flag ordering on 'task create' - Clean up test tasks polluted
in production database

All 29 tests passing.
