Workflows written below Mendix 11.3 load and pass mx check

mxcli wrote every workflow in the Mendix 11.3 shape: the main flow's start and closing end stored as activities, and layout properties on every activity. mxcli check and exec passed, but below 11.3:

Mendix	Symptom
10.24, 11.0	The project no longer loads: TypeCacheUnknownTypeException … Workflows$StartWorkflowActivity. The type is introduced in 11.1.0.
11.1, 11.2	CE6671 and CE6689. These versions have the type but keep the main flow's start and end implicit. 11.3 is the first to store them.
below 11.1	Every activity carried RelativeMiddlePoint/Size, which Workflows$WorkflowActivity declares only from 11.1.0. That includes an activity inserted by alter workflow … insert.

Fix

• The encoder writes the shape the project's version stores.
  • Below 11.3, it drops the main flow's start and closing end. The header's annotation becomes the workflow's own note. A branch's end workflow stays.
  • Below 11.1, it drops the activity geometry in create, create-or-modify and the activity alter workflow … insert adds.
• alter workflow … set (Annotation: …) writes the workflow's own note when there is no start activity to hold it.
• The CREATE OR MODIFY guard counted branch ends as "all stored Ends − 1". Below 11.3 that silently dropped a branch's end workflow on a rewrite. It now subtracts the main End only when one is stored.
• Property-set defaults: 10.24's mx convert adds UsertaskOnStateChangeEvent and WorkflowOnStateChangeEvent to every workflow. That was measured on 10.24 and 11.0 and is now in the defaults table.

Why CI missed it

• 24-workflow-examples.mdl is gated 11.0+ as a whole file, so the nightly 10.24 leg never wrote a workflow.
• The matrix's lowest 11.x, 11.6.8, is past both version boundaries.
• The new 24b-workflow-mendix10-examples.mdl is gated 10.0+. On its first run it found the guard and property-set gaps above.

Verified

• Unit tests: written first, red then green. They cover the shape per version (with 11.3, 11.14 and unread-version controls), the geometry (with an 11.1 control), the inserted activity, the note without a start, and the guard.

• Real mx check of the bug-test script on fresh apps: blank app, then the fixed build, then the fixed build with both version predicates stubbed true:

  Mendix	blank	fixed	stubbed
  10.24.24	0	0	TypeCacheUnknownTypeException
  11.0.0	0	0	TypeCacheUnknownTypeException
  11.1.0	0	0	CE6671 + CE6689
  11.3.0 (control)	0	0	0

• Round trip on 10.24: executing the describe workflow output reports "Unchanged workflow" and leaves no unit bytes changed.

• Local checks: make build, make test, make lint and make check-mdl pass, along with the findings, skill-index and wiki-page checks
