Fixes the /compress reference card showing only a short 3-line summary immediately after compression. Now prefers the persisted compaction message (full handoff) over the raw API summary, matching what is shown after page reload. Closes #695.
POST /api/session/compress with optional focus_topic. Transcript-inline cards: command, running, complete (collapsible green), reference. /compact alias kept. Fixes: var(--green) undefined color, focus_topic 500-char cap. Independent review by @nesquena (4 passes).
