refactor(buffer): split extmark namespace into ns_eol and ns_inline

Browse source 
Problem: all extmarks shared a single `pending` namespace, making it
impossible to selectively clear position-sensitive extmarks (overlays,
highlights) while preserving stable EOL virtual text (due dates,
recurrence).

Solution: introduce `ns_eol` for end-of-line virtual text and
`ns_inline` for overlays and highlights. `clear_marks()` and
`apply_extmarks()` operate on both namespaces independently.
