When a workflow spans multiple TM1 instances, sessions are now released as soon as an instance has no pending or running tasks, rather than waiting for the entire workflow to complete. This significantly reduces exclusive mode blocking time for multi-instance workflows. Closes #135 Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Early release was deleting entries from tm1_services, which broke integration tests that share the dict across test methods via setUpClass. Now tracks released instances in a local set instead. Also splits CI TM1 config into variable (connection details) + secret (password only) for better visibility and debugging. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
… connections
Early release must only fire when tm1_preserve_connections is explicitly
passed (i.e. from CLI). Integration tests share TM1Service objects across
test methods via setUpClass — logging out a shared service corrupted the
HTTP session state ("multiple cookies with name TM1SessionId").
