Unified tool call display schema, compaction timeline, and auth fixes

- Replace extractPrincipalParam, parseToolCallDisplay, getToolKindFromName
  with a single unified parseToolCallDisplay on the server, consumed by
  both server (activity-curator) and app
- Parse tool calls exactly once and pass ToolCallDisplayInfo down to all
  consumers (message, sheet, details, stream view)
- Add compaction timeline item: detect SDKStatusMessage (compacting) and
  SDKCompactBoundaryMessage, show loading/completed marker in timeline
- Suppress compact summary user message in live stream (flag) and JSONL
  resume (isCompactSummary check)
- Add CompactionMarker component with scissors icon and token count
- Hide sub-agent tool calls from timeline, collapse into Task metadata
- Add Bot icon for Task tool calls
- Fix stripShellWrapperPrefix to strip /bin/zsh -lc wrappers without cd
- Replace CLAUDE_SESSION_TOKEN with CLAUDE_CODE_OAUTH_TOKEN
