Add click-channel workflow harness for New, Sketch/Pad, and Export

[jkbennitt]

Adds a CI-safe operator harness that clicks real VibeCAD controls through the existing authenticated loopback channel.

Upstream PR (the one requested): 10-X-eng#242

AppSprout-dev/vibecad main was fast-forwarded to 10-X-eng/vibecad main at 3fb66124 before this branch. No merge commit was required.

What this checks

Three workflows go through POST /v1/ui/click / VibeCADAgentCli ui-click. They do not move the OS cursor.

1. New document — command VibeCADRibbonNew (Std_New). Asserts a semantically verified click, document count +1, and an active document.
2. Sketch then pad — New document, ribbon Model, Sketcher_NewSketch, PartDesign_Pad. Asserts the Model tab, then sketch and pad document objects.
3. Export — New document, command Std_Export. Asserts a semantically verified click with an active document still present.

Invoke-VibeCAD-VisibleTour.ps1 stays the human-watchable demo. This harness is the workflow suite.

Jev

Optional, default off. After a step, one System One request may classify landed (Noul), failure_class (Choice: geometry_bug | wrong_button | model_lied | flake), and progress (Score). Code owns click, timeout, and pass/fail. Low confidence cannot turn a green step red. A live call happens only when both VIBECAD_JEV_JUDGE=1 and TYPESAFE_API_KEY are set. CI mocks or skips. No key is committed.

GitHub Actions runs the fake-channel assertions. A full FreeCAD GUI e2e is not required for CI green.

Test plan

• PYTHONPATH=src/Mod/VibeCAD python -m pytest -q src/Mod/VibeCAD/vibecad_tests/test_workflow_harness.py
• PYTHONPATH=src/Mod/VibeCAD python src/Mod/VibeCAD/VibeCADWorkflowHarness.py --fake-channel
• Existing ribbon/menu click contract tests still pass.

Compatibility

• Existing public functions/APIs still present and behaviorally compatible.
• No preference keys, tool names, or schema fields renamed/removed without approval.
• Defaults preserve previous behavior for users who do not opt into new features.
• Deprecations (if any) are documented and dual-path supported.
• Breaking changes are listed with owner approval reference.

/v1/ui/click still accepts kind=ribbon|menu. kind=command is additive.
