Remove the version checks around add_note()

[pyedaa-claude]

Bug Fixes

• All 18 Exception.add_note() call was wrapped in if version_info >= (3, 11):, so the note was attached only on
  Python 3.11 and newer. This package requires Python 3.11 or newer
  (setup.py: pythonVersions=("3.11", "3.12", "3.13", "3.14")), so the condition is always true and the guard is a
  leftover from supporting 3.10.

  ex = TypeError(f"Parameter 'name' is not of type 'str'.")
  ex.add_note(f"Got type '{getFullyQualifiedName(name)}'.")
  raise ex

• The # pragma: no cover markers go with them: those lines were never covered because the false branch cannot be
  reached, and marking reachable code as uncoverable hides it from the coverage report.

Changes

• from sys import version_info is dropped where nothing else used it.
• A commented-out block carrying the same guard was updated with the others, so it doesn't reintroduce the pattern when someone uncomments it.

Unit Tests

• Not run: pyEDAA.IPXACT does not import on dev - pyEDAA/IPXACT/__init__.py:165 uses _IPXACT_10_INDEX and
  eight more _IPXACT_*_INDEX names that are never defined, so every testcase fails collection with a NameError
  before and after this change (7 collection errors on both). The modules compile, and the change is mechanical.
  Reported separately - it means the package is currently unusable.

Related Issues and Pull-Requests

• Same cleanup in pyTooling (#277), pyEDAA.ProjectModel and
  pyEDAA.Reports, following a review comment in
  pyTooling#274: "pyTooling is Python 3.11+, so no version check
  is required."
