v0.47.9

Make the session map legible for heavy parallel / workflow runs (driven by viewing a real 96-lane workflow).

• Lanes read as roles, not paragraphs. A workflow fans out dozens of subagents; the transcript-only ones had only their first prompt to label with. Each lane is now named by its role — the spawn type (general-purpose, workflow:urp-report-korean), or distilled from the task prompt ("You are a literature-search specialist…" → literature-search specialist; "너는 내용 충실성 감사관이다…" → 내용 충실성 감사관). Applied at render (so runs recorded before this read as roles too) and in the adapter (new recordings store the role). graph.ts is now the sole authority on a lane's display name and prefers the concise spawn role over a long prompt label.
• Dense runs open at a readable zoom instead of fit-to-tiny; the % button still resets to 100% = fit the whole tree, so the full picture is one click away.
• A finished run's lanes read DONE, not stuck on ACTIVE (subagent transcripts rarely emit a clean end, so the node status used to stick).

245 tests pass; verified live on a 1429-event / 96-lane workflow run.
