The selection scenario now receives the current score order and uses it when resolving the order returned by the selection dialog. Part insertion recalculates instrument numbers across the requested part list. Instrument-scene tree operations now handle shared parts in additional paths, and staff visibility checks both staff and part visibility. The change also adds selection scenario tests and CMake configuration for those tests.

Clear the shared part in resetAllFormatting as well.
resetAllFormatting clones the master part and inserts the clone into an excerpt without clearing sharedPart. While the shared part is enabled, Part::show() hides the reset instrument in that excerpt.
Suggested fix

- notation()->parts()->replacePart(id(), masterPart->clone());++ // The clone would keep the master score's shared part, which doesn't exist in this excerpt+ Part* part = masterPart->clone();+ part->setSharedPart(nullptr);++ notation()->parts()->replacePart(id(), part);

Add a test where a customized score order is cleared by the dialog.
SelectInstruments_CustomizedFlag_ComesFromDialog only checks the true direction: the dialog returns customized=true and the result is true. Every source order in the suite starts uncustomized. A regression that keeps a source order's customized=true when the dialog returns false would pass the suite. Add a case where the score's own order is customized and the dialog returns false. The test must use a non-built-in order id. For a built-in id, the scenario returns the repository order instead of the score's order.

Enable the instruments scene module in the UTEST block so its tests run.
The UTEST block without code coverage sets MUE_BUILD_INSTRUMENTSSCENE_MODULE to OFF. The test subdirectory is added only from inside the real module, so instrumentsscene_tests is never configured. Keep the module enabled in that block. The status message in that block asks for this when tests are added to a module.

Reject layer drops onto shared-part rows that the active notation lacks.
resolveDstStaff now accepts SHARED_PART rows. When the excerpt lacks the part, PartTreeItem::part() returns the master part, so staff(0) returns a master staff. moveChildrenOnScore finds no such staff in the excerpt and skips the score move. The tree row still moves. Resolve the destination only when the active notation contains the part, and cancel the move otherwise.

Count shared-part rows when checking part order.
partsOrderWillBeChanged counts only PART rows. A move across a SHARED_PART row therefore takes the system-object path. The markings move to the shared part's staff, and moveParts never runs. The score keeps its part order while the tree changes. Count isPartItem rows in both loops, and check that buildPartsMoveParams handles shared-part destinations.

Disable staff visibility changes while the origin instrument is combined.
The staff row under a combined origin instrument keeps its own enabled state, so its visibility button stays usable. Clicking it stores hidden visibility on the origin staff, which stays hidden after the instruments are separated. Make the staff row unavailable for visibility changes while the origin part's shared part is enabled.

Keep a unique number for a digit-ending instrument name.
When an existing instrument with the same ID has a digit-ending long name, such as "Flute 2", resolveInstrumentNumbers gives that part number 0 but still counts it. A new instrument with the same ID then gets number 2. Both instruments render as "Flute 2". Before this change, the existing part rendered as "Flute 2 1", so the labels were distinct.
Choose a numbering rule that keeps labels distinct. A safe localized edit is not established, so no diff is proposed.
