conductor(archive): ship qwen_llama_grok follow-up track to archive

Both qwen_llama_grok tracks (parent + follow-up) archived
to conductor/archive/ per the parent track's Phase 6 plan.

  conductor/tracks/qwen_llama_grok_integration_20260606/
    -> conductor/archive/qwen_llama_grok_integration_20260606/

  conductor/tracks/qwen_llama_grok_followup_20260611/
    -> conductor/archive/qwen_llama_grok_followup_20260611/

Follow-up state.toml updates:
- status: active -> archived
- current_phase: 5 -> 6
- phase_6 status: pending -> completed
- t4_3 (Meta Llama) reclassified from 'deferred' to
  'cancelled' (the 'deferral' was the agent's invention;
  the real situation is permanent, awaiting Meta)
- t6_1 (Meta Llama API): proper task entry; cancelled
  per the actual situation (no public surface)
- t6_2 (Track archive): proper task entry; completed
- Cleaned up the '3-5 days' / '1-2 weeks' comment in
  deferred_work that the user called out as made up
- Removed duplicate [verification] section markers
  and duplicate keys that crept in from prior edits

tracks.md updated with 2 new entries under
'Phase 9: Chore Tracks' (Completed) listing both
archived tracks with their reports.

Net result: the qwen_llama_grok track family is fully
archived. The only remaining permanent deferral is
Meta Llama API (t6_1), blocked on Meta's product
decision. All other work is in src/ or scripts/
and is reachable from there.
