feat: Add Custom Notes feature for uninstaller entries

[ronimuliawan]

• Added CustomNotesManager to save and load notes persistently via XML (CustomNotes.xml).
• Injected CustomNote property into ApplicationUninstallerEntry to bind notes directly to entries.
• Created CustomNoteDialog UI to allow users to view and edit notes.
• Added a "Custom Note" column to the main uninstaller list view.
• Added an "Edit Custom Note..." option to the right-click context menu in the main window.
• Fixed legacy MSTest compilation errors in DrawingToolsTests and UninstallListTests for .NET 8 compatibility.

Resolves #932

Some images on how it works

Image 1: this is the UI for adding new custom notes Image 2: this is the UI for adding new custom notes, after typing and clicking ok, it will get saved Image 3: double clicking on items Image 4: this is the UI for editing existing custom notes, all text selected by default

Pardon for the washed color on the screenshot, HDR. Hmm.
Anyway, this is my first time ever to contribute to an open source project, if I made a mistake along the way, let me know so I can learn something new.

I made some changes that probably I could have avoid:

1. source/BulkCrapUninstallerTests/DrawingToolsTests.cs
2. source/BulkCrapUninstallerTests/UninstallListTests.cs

especially on number 2, this is probably due to my visual studio build tools version, I am using 2026 and I can't install 2022 due to limited disk space and internet quota (I'm on the road right now), the build process kept throwing error around those codes.

Functionally looks fine but there's some issues and oddities that prevent a merge.

I think the way the notes are implemented currently they have a very limited use since you cannot see the note or even know that the note exists by looking at the application list.
You have to know that there is a note for that specific item and manually open the note editor to read it, but if you remember there is a note you probably also remember what the note is saying.

I don't know how to resolve this, but as it is now it's unlikely to be used much. Maybe it could be shown on the left sidebar when selected, or in a tooltip on mouse hover. It could also show an extra note icon for the uninstaller entry, and hovering over that would show the tooltip? I'm open to discussion and different takes on this.

Pull from upstream to fix the failing check.

on the app list you can see it at the very right side of things, which can be dragged if needed. I intentionally create a very bare minimum working feature without thinking of adding any special icons and other UI elements, so you can give me some inputs about how you do things around here, a little bit discussion and maybe a couple of commits later we are good to go. Tbh, I don't really know what I should add because this is my very first time contributing to any open-source project, so I decided to just took the description of the issue very literal

thanks for all the feedback, I have read them all carefully, I will make some adjustment and get back to you

dang this is exiciting

all issue has been addressed, I also added a comment on each comment you made. I tried running the action on my fork, it passed

Good changes. I think the current column approach is good enough to merge.

The edit custom note item should be moved above Properties I think, It can be named simply "Edit note...".

Once this review is addressed it should be good to merge.

[ronimuliawan]

Suggestions to add for custom note, just pushing it a little bit further:

1. Sequential Popups: bulk change but every single apps can have different notes, example: app A, B, C, D, E are selected, but app A has note "This is used for windows development". app B has note "This is used for rust development", app C has note "This is used for android development", app D and E has the same note "This is a must have for any development work". Note for app E can be the same as app D by checking a box called "Same Note as the previous app (App Name Here)" which NOT selected by default, the default text for the note should be empty if it's a new note, or what's in there previously if the user already has note.
2. Multi-Edit Grid: like no 2 but instead of treating it like a questioner or survey, just show all 5 of the and then the user can edit all of it simultaneously.

a must have for these 2 features is a HARD cap on how many apps can be selected at any given time. The maximum amount a user can select and edit, should not be more than 6.

Because:

• protecting from crash due to miss click, 100+ popups is a nightmare to cancel and might lead to a crash (just my opinion).
• limited UI space for multi-edit grid. Having 10+ editing grid is weird..

what do you think? if it aligns, I can create a new PR just for this 2 features.

All good, thank you for the PR!
