feat: get_categories tool, author resolution in get_activities, update CLAUDE.md (v0.4.8)

- get_categories(list_id): new tool filtering taskcategorysync by
  sortingIndexByTaskList, returns {id, name, emoji} ordered by sort index
- get_activities: author IDs now resolved to display names (firstName) via
  famlistfamily members; raw author_id preserved as separate field; member
  lookup is non-fatal (falls back to raw ID on error)
- CLAUDE.md: tools table updated to reflect all implemented tools (v0.4.8)
- SPEC.md: full accgetallfamily response structure documented including
  categories[] on tasks and category parameter investigation findings
- Category assignment in create/update task: all tested parameter names
  ignored by API; still to verify (Service Worker blocks web inspection)
