An operator hit "Значение не может быть неопределенным. Имя параметра:
source" (ArgumentNullException, ParamName=source) opening the bulk
sender window on a real Outlook install. A full read-through of every
LINQ call reachable from that path found nothing that could receive a
null source, and this dev machine has no Outlook to reproduce against
- so the next occurrence needs a real stack trace to diagnose instead
of guessing from ex.Message alone.

First live build against real Visual Studio/VSTO tooling surfaced two
issues in the hand-written AddIn scaffold: ThisAddIn derived from the
wrong base type (OutlookAddIn is an interface, not the concrete
OutlookAddInBase class), and VSTO Application projects cannot build
without a signed ClickOnce manifest, so SignManifests is now on with a
throwaway self-signed test certificate. Both Core/Core.Tests/AddIn now
build clean and Core.Tests passes.
Also: mail always sent from Outlook's default account with no way to
pick a different one (e.g. a shared mailbox) - added a "From account"
setting (Session.Accounts dropdown in SettingsForm, SendUsingAccount in
MailSender). And added deploy/ with both a local ClickOnce publish
script (real install/uninstall via Windows Apps, no manual registry
editing) and a manual registry sideload fallback for scripted rollouts.
