Press [ in detail view to open link picker showing all [[links]] in the current entry. Enter follows a link, resolving by title then body substring. Navigation history stack enables esc to pop back through followed links before returning to list. Adds Store.ResolveLink() for non-transactional link resolution from the TUI layer.
