Adapt the speed dial's ActionRegistry to the collapsed
get_plugin_capability(PluginCapabilityId) overload, and restore the
script success/skipped status message the dialog lost when its
PluginScriptRunner refactor was superseded by ActionRegistry.
Plugins dialog and the Speed Dial popup each
carried a private copy of the same fuzzy
matcher and had already drifted. Move the
pure functions into a shared module loaded
by both pages, and add a unit test beside
it.
Replace the toolbar sort dropdown with sortable Name/Source/Status column
headers that cycle ascending, descending, then clear. Add a Source column
and a PluginSortKey::None baseline for the cleared state. The whole header
cell is the click target and the sort triangle snaps in without a fade.
