Merge pull request #392 from Molecule-AI/fix/wcag-node-and-traces-text

Code review passed:
- WorkspaceNode.tsx: 3 × text-[7px]→text-[9px] on status badge, active-task count, currentTask banner — correct targets; decorative text-[7px] (tier badges, skill overflow +N, Team header, font-mono) correctly left unchanged
- TracesTab.tsx: 2 × text-zinc-600→text-zinc-500 on token count + expand chevron — correct; line 72 empty-state dim label correctly left at zinc-600
- 485/485 tests pass with changes applied
- Pure class-string changes, no logic affected
LGTM — merging.
