v3.3.0 - Enhanced Verification, QML Tokens & Core Hardening

Highlights in v3.3.0

• Backend & Core Hardening:

  • File lock descriptor cleanup in scripts/state_utils.py safeguarded against leak edge cases.
  • Added compilation checks for state_utils.py in scripts/check.sh.
  • Configurable PYTHON interpreter resolution across virtual environments and CI workflows.
  • Enhanced cache and temp directory pruning (.ruff_cache, .mypy_cache) in package hygiene gates.

• Frontend & QML Tokens:

  • Standardized chevron navigation icons to use Icons.glyph() instead of raw literal codepoints.
  • Removed dead operationOrigin property in Panel.qml.
  • Aligned schedule validation locale propagation across editor methods.

• Documentation & Architecture:

  • Redesigned and streamlined README.md with Mermaid architecture diagrams, module breakdown tables, and dual-localization guides.
  • Removed redundancy and marketing filler for a dense, factual reference.

• Quality Gates & Tests:

  • 100% test pass rate across 171+ Python tests and 107 Node test assertions.
