feat(buffer): add PendingRecur highlight and recurrence virtual text

Browse source 
Problem: recurring tasks have no visual indicator in the buffer,
and the extmark logic uses a rigid if/elseif chain that does not
compose well with additional virtual text fields.

Solution: add PendingRecur highlight group linking to DiagnosticInfo.
Refactor apply_extmarks() to build virtual text parts dynamically,
appending category, recurrence indicator, and due date as separate
composable segments. Set omnifunc on the pending buffer.
