Guard the curriculum source before legacy-state migration.
main calls migrate_legacy_state_dir before _cmd_init, while init_workspace performs the same-source check later. If the source checkout contains .pylings but not .pythonlings, migration renames .pylings to .pythonlings before the guard rejects init --force. The current test has no legacy state, so migration is skipped and the regression is undetected. Add that legacy-state case and perform the source check before migration.

Fix the physical newlines in the added string literals.
Both test modules fail Python parsing because the affected quoted strings contain physical newlines. Replace them with escaped \n sequences.

Summary
pythonlings init --path <curriculum-source> --forcecopied the packaged curriculum onto itself and raisedshutil.SameFileErrorwith a traceback.update_workspace()already rejected that target;init_workspace()did not.Motivation
Fixes #71.
Implementation
In
init_workspace(), resolvesource_root()and raiseWorkspaceErrorwhen the destination is the same path, beforemkdiror any copy. The CLI already printspythonlings: {error}and exits 1 forWorkspaceError, so no CLI change was required.Forced init of a different existing workspace, first-time init, and non-forced init are unchanged.
Testing
25 passed.
Also ran the non-TUI unit/integration suite (165 passed; one pre-existing failure in
test_cli_doctor.pybecausepython -m pythonlingsis not installed in the test environment). TUI tests were not collected here (textualnot installed).Summary by CodeRabbit
