Simplify traversal example to December 2024

Shorter example (5 fetches vs 8) still demonstrates key concepts:
- Pre-computed prev-security links
- Automatic year boundary crossing (2025/01 → 2024/11)
- Stop condition

 The `prev-security` links are pre-computed at publish time and cross year boundaries automatically (e.g., `2025/01` → `2024/11`). Following them is O(security-months), not O(all-months). Once you have the first month, no additional year index fetches are needed.

 **Anti-pattern:** Do not fetch multiple year indexes to inspect `_embedded.months[]` and plan which months to fetch. The `prev-security` chain crosses year boundaries automatically — just follow it.
