Group Queue Exact, Apply Selected, and Clear Selected into a single
'Link' dropdown menu in the missing browser footer. Move Auto-Link 100%
into the same menu and show/hide it when exact local matches exist.
Add disabledWhen support to createFooterMenu items so buttons can be
visually and functionally disabled. Include disabled state styles for
.mr-footer-menu-item.
Simplify footer visibility logic and update references throughout.
Replace all link dialog terminology with resolver terminology
throughout the codebase, including module names, CSS classes,
IDs, JS variables, SVG gradient IDs, and log module names.
Remove the old web/linker/ tree and introduce the new web/resolver/
tree with parallel structure. Also replace core/linker.py with
core/resolver.py.
