minimal home: the buttons carve out of the drag band; own-line summary (release polish 2.3)

Owner report (Electron): the Chains and Import-notes buttons were not
clickable — clicking dragged the window. Root cause: the chrome column
lacked lh-no-drag. The drag mask resolves by DOM order, and the graph
chrome's column carries the carve exactly for this reason (the
2026-09-17 mask law). The minimal home's column now carries the same
class on the same shape — byte-for-byte the graph chrome's law — and
the pointer-events juggling is gone (it was browser-thinking; Electron
needs the region carve, not the pointer filter).

Summary refinement (owner, same round): every count on its OWN line —
no dot separators; the two blocks (propositions/chains, teaching/
practice sessions) part with one empty line (a dedicated h-4 spacer);
imported notes render as a COUNT ("4 imported notes"), never the file
list. KnowledgeSummary's contract changes sources: string[] →
importedNotes: number.

1419 tests (own-line pins: no " · " anywhere, h-4 parting, count-not-
paths, singulars); tsc, lint, build green.
