- Add border-r border-[var(--sidebar-border)] to PulseView container
- CommitCard files default to collapsed (expanded: false) for cleaner initial state
- Update tests to reflect new collapsed-by-default behavior
Adds a new Pulse sidebar section that shows chronological git commit
history for the vault. Commits are grouped by day with message, time,
short hash (clickable GitHub link when remote configured), file list
with add/modify/delete status icons, and summary badges. Clicking a
file opens the note in the editor. Disabled with tooltip for non-git
vaults. Accessible via sidebar click or "Go to Pulse" command palette.
