feat(cli): add --wait flag for consolidate and --date filter for document list

[slayoffer]

Summary

• bank consolidate: Add --wait flag to poll for operation completion status instead of returning immediately
• bank consolidate: Add --poll-interval option (default 10s) to control polling frequency when using --wait
• document list: Add --date filter to show documents by date (yesterday, today, YYYY-MM-DD, or all)

Usage Examples

# Wait for consolidation to complete
hindsight bank consolidate my-bank --wait

# With custom poll interval
hindsight bank consolidate my-bank --wait --poll-interval 5

# List documents from yesterday (default)
hindsight document list my-bank --date yesterday

# List today's documents
hindsight document list my-bank --date today

# List documents from a specific date
hindsight document list my-bank --date 2026-01-15

# List all documents grouped by date
hindsight document list my-bank --date all

Test plan

• Test hindsight bank consolidate <bank> --wait polls until completion
• Test hindsight document list <bank> --date today filters correctly
• Test hindsight document list <bank> --date 2026-01-30 filters by specific date
• Test hindsight document list <bank> --date all shows all documents grouped by date
