consolidate-full: autonomous consolidation pipeline

New commands:
- `digest auto`: detect and generate missing daily/weekly/monthly
  digests bottom-up. Validates date format to skip non-date journal
  keys. Skips today (incomplete) and current week/month.
- `consolidate-full`: full autonomous pipeline:
  1. Plan (metrics → agent allocation)
  2. Execute agents (batched Sonnet calls, 5 nodes per batch)
  3. Apply consolidation actions
  4. Generate missing digests
  5. Apply digest links
  Logs everything to agent-results/consolidate-full.log

Fix: separator agent prompt was including all interference pairs
(1114 pairs = 1.3M chars) instead of truncating to batch size.

First successful run: 862s, 6/8 agents, +100 relations, 91 digest
links applied.
