- Calendar overnight events render proportionally across day boundaries
via --start-frac / --end-frac CSS vars instead of bleeding as full-day
on day 2.
- Recurring-event delete strips the master uid + all master::* sibling
instances optimistically so the row clears immediately instead of
waiting for the next sync re-render.
- manage_notes(create) now returns note_id + open_url, and agent_loop
appends a markdown [View note](#note-<id>) link mirroring the
deep-research pattern.
- chatRenderer's hash-link router (already wired for #note-id) reaches
the new notes.openNote(id) helper, which force-closes/reopens the
Notes panel, polls for the target card, and runs a brief outline
flash so the user can locate it on long lists.
