Description

This PR fixes TMPRL1101 workflow deadlock risk caused by using process Loguru logger inside Temporal workflow threads.

Changes:

• Add WorkflowRuntimeLogger adapter in tracecat/dsl/workflow_logging.py.
• Route DSL workflow/scheduler logs through Temporal workflow logger when in workflow context.
• Keep process logger fallback for non-workflow contexts (unit tests/local usage).
• Reduce high-frequency workflow/scheduler log volume (info -> debug) in hot paths.
• Add unit tests for workflow logging adapter behavior.
• Add deterministic local repro harness: scripts/temporal/repro_workflow_logging_deadlock.py.
• Remove unused workflow-side ctx_logger/process_logger wiring from DSLWorkflow.

Steps to QA

1. Run targeted checks:
   • uv run ruff check tracecat/dsl/workflow.py tracecat/dsl/scheduler.py tracecat/dsl/workflow_logging.py tests/unit/test_dsl_workflow_logging.py scripts/temporal/repro_workflow_logging_deadlock.py
   • uv run basedpyright tracecat/dsl/workflow.py tracecat/dsl/scheduler.py tracecat/dsl/workflow_logging.py tests/unit/test_dsl_workflow_logging.py scripts/temporal/repro_workflow_logging_deadlock.py
2. Run unit tests:
   • TRACECAT__SERVICE_KEY=dummy uv run pytest tests/unit/test_dsl_workflow_logging.py
   • TRACECAT__SERVICE_KEY=dummy uv run pytest tests/unit/test_schedule_role_healing.py
   • TRACECAT__SERVICE_KEY=dummy uv run pytest tests/unit/test_dsl_scheduler_determinism.py
3. Run deadlock repro harness:
   • uv run python scripts/temporal/repro_workflow_logging_deadlock.py --mode both --block-seconds 2.5
4. Verify expected repro output:
   • Legacy path reports TMPRL1101 in workflow task history.
   • Safe path completes with no TMPRL1101.

Summary by cubic

Fixes Temporal workflow deadlocks (TMPRL1101) by switching DSL logs to a workflow‑safe logger, deferring formatting with lazy callables, and gating formatting behind level checks to prevent blocking in workflow threads. Adds tests and a hardened local repro script to reliably reproduce and validate the fix.

• Bug Fixes

  • Added WorkflowRuntimeLogger and get_workflow_logger to use Temporal’s logger in workflow context with a process logger fallback; maps trace to debug, skips field formatting when the level is disabled, and uses Loguru lazy callables to defer message/field formatting.
  • Routed DSL workflow and Scheduler logs through the workflow‑safe logger; added optional logger injection; lowered hot‑path info logs to debug and adjusted warnings where appropriate.
  • Hardened repro harness: checks workflow history for TMPRL1101, installs/removes a blocking sink safely, supports mode/block‑seconds flags; expanded tests for context detection, trace mapping, safe repr, disabled‑level gating, and lazy callables.

• Refactors

  • Removed installed site‑packages tarball build; always build the venv tarball from the builtin source path, and deleted the TRACECAT__REGISTRY_SYNC_BUILTIN_USE_INSTALLED_SITE_PACKAGES flag.
  • Removed unused ctx_logger wiring from DSLWorkflow and routed logging through the new workflow‑safe adapter.
