* fix: move draft and template context handling out of create_workflow_run
create_workflow_run now only creates
the run with the definition_id and initial_context provided by the caller. Test call paths explicitly resolve draft definitions
and merge template context variables before creating the run, while production/runtime paths bind the published definition
without adding template defaults.
* fix: review comments
* chore: format and minor cleanups

* fix: disable duplicate trigger nodes in workflow builder
AddNodePanel: disable trigger buttons and show tooltip when a trigger
already exists on the canvas, using bySpecName to identify trigger-
category specs from the live node list.
useWorkflowState: preflight in saveWorkflow rejects saves with multiple
trigger nodes via a sonner toast before the network request is made.
text_chat_session_service: include the original exception message in
TextChatSessionExecutionError so the HTTP 500 detail surfaces the root
cause without DB inspection.
Closes#378
* style: format test_text_chat_session_service.py with ruff
* chore: retrigger CI checks
* fix(workflow): enforce node instance constraints
