Fix #32422: changing pitch on TAB staff also applies to tied notes - #35541
This changes the behaviour when selecting a note that has tied notes, on a TAB staff, and changing the fretting (from 5 to 3, for example). Previously, it only updated the tied notes on the TAB staff visually, in the layout, i.e. it didn't change the actual pitch of the note. It now does, and it also correctly updates the linked notes (the notes on a regular staff, for example) and its tied notes too.
There are 3 tests that test this behaviour when changing the first note on the TAB staff, the second (tied) note, and the first note of the regular staff.
Each commit's message describes its purpose and effects, and references the issue it resolves. If changes are extensive, there is a sequence of easily reviewable commits.
The code compiles and runs on my machine, preferably after each commit individually. I have manually tested and verified that my changes fulfil their intended purpose.
No prior attempts to resolve this problem exist, or if they do, I listed them in my PR description and described how I avoided repeating past mistakes.
Complete only if applicable:
I created a unit test or vtest to verify the changes I made.
This PR was created using AI assistance; I have read, understood and complied following the guidelines for AI-assisted contributions. The AI tool(s) I used are listed below.
When changing fret on a string in a TAB staff, change tiedNotes()
correctly too, also for linked notes, so the regular staff also updates.
Add 3 tests that test behaviour when changing the first note on the TAB
staff, the second (tied) note, and the first note of the regular staff.
TAB fret entry now updates the pitch, string, fret, and default TPC values of each note in the tied chain. New tests cover fret changes at both ends of a tie, a standard-staff pitch change, and pitch spelling across key signatures on linked tablature and standard staves.
Severity of issue fixed: Medium
Merge Risk: Low · up to abac3
The change is mergeable with awareness that pitch edits may leave a D.S. partial-tie source unchanged in a specific tie configuration.

Explanation
[#32422] Fret entry now updates tied notes and their linked notes. Tests cover the first and last TAB notes, standard-staff chromatic editing, and spelling across a key change. The available code evidence does not establish whether TAB chromatic editing updates the full linked tie chain. It also does not establish whether fret-digit combination uses only the target string in a chord.
Resolution
Provide focused code or test evidence for TAB chromatic editing across linked tie chains and for fret-digit entry in chords with multiple strings.

Include the partial-tie source in the pitch update.
When a full tie ends at a segno destination also reached by a D.S. partial tie, tiedNotes() omits the D.S. source. Editing the first TAB note changes the full tie but leaves the D.S. note at its old pitch. Include that source in the update.

Correct me if I'm wrong, but I feel this is slightly out of scope for this PR. It seems it is existing behaviour for tiedNotes(), so it would mean changing tiedNotes(), which is perhaps a bigger change than just the TAB behaviour in this PR. Can the helpful little AI rabbit make an issue for this, perhaps? 🐇

This is a follow-up to the partial-tie review discussion on #35541, separate from that PR's TAB tie-chain fix for #32422.`Note::tiedNotes()` backtracks with `firstTiedNote()` and then traverses forward with `findTiedNotes()`. The shared traversal implementation is unchanged by #35541. The review identified a possible omitted incoming D.S. source when traversal starts from the full-tie source.## Scenario to reproduce1. Create notes A and B with a full tie from A to B.2. Place a segno at B's location.3. Add a later note C with a D.S. partial tie that reaches B.4. Use linked standard and TAB staves.5. Change A's fret on the TAB staff.6. Check the actual pitches of A, B, C, and their linked notes.The reported concern is that A and B change pitch while C retains its previous pitch. This report is based on source inspection, not a runtime reproduction. Confirm the behavior and the affected versions before treating it as a confirmed regression.## Required investigation and changes- Confirm whether `Note::tiedNotes()` omits C when invoked from A in this topology.- Determine the intended pitch-edit semantics for incoming partial-tie sources that share a destination with a full tie.- If all connected notes should change, update shared traversal or the appropriate pitch-edit operation to include the incoming source.- Preserve TAB string matching and linked-staff behavior.- Avoid duplicate updates and cyclic traversal.- Add regression coverage for the shared-destination topology.A change to `Note::tiedNotes()` is one possible solution, not a required implementation. Check other callers before changing its contract.## Affected areas- `src/engraving/dom/note.cpp`: `Note::firstTiedNote()`, `Note::findTiedNotes()`, and `Note::tiedNotes()`.- `src/engraving/dom/tie.cpp` and `src/engraving/dom/tiejumppointlist.cpp`: partial-tie jump relationships.- `src/engraving/editing/noteinput.cpp`: TAB fret-entry updates.- `src/engraving/editing/editnote.cpp`: pitch and fretting updates.- `src/engraving/tests/partialtie_tests.cpp`: existing `segnoBefore` and `segnoAfter` scenarios provide topology examples.- `src/engraving/tests/note_tests.cpp`: linked-staff pitch-edit regression coverage.## Acceptance criteria- A regression test establishes the expected pitch behavior for A, B, and C.- Under the agreed semantics, pitch edits keep the connected notes and linked staves consistent.- TAB fret values remain consistent with the resulting pitches.- Undo and redo restore and reapply the complete edit.- Ordinary full ties and existing partial-tie scenarios still work.- If shared traversal changes, tests cover duplicate prevention and cycle safety.## ContextRequested by @valentijnnieman.- PR: https://github.com/musescore/MuseScore/pull/35541- Review discussion: https://github.com/musescore/MuseScore/pull/35541#discussion_r4492277891EOF)"

@valentijnnieman Agreed. The shared tie-traversal implementation is unchanged by this PR, so a separate follow-up is appropriate. The follow-up can determine whether to change tiedNotes() or handle this case in the pitch-edit operation.
Created #35545 with the reported scenario, affected code, test criteria, and links to this discussion. The issue notes that runtime reproduction is still needed.
