Repoint home.md ePub TODO away from retired llm-wiki/

Why Track This

The legacy llm-wiki/ directory was retired on 2026-06-27 (commit b69ff23ae4).
A leftover TODO in home.md (line 175 — "TODO View ePub from file location in
llm-wiki") still references that retired path. It is the user's planning note, so
it was intentionally not auto-edited during retirement; it stays here as a
tracked follow-up rather than a silent edit.

Current State

• home.md:175 reads: 3. TODO View ePub from file location in llm-wiki
• llm-wiki/ no longer exists (recoverable from git history).
• The ebooks themselves still live in the per-book directories in the repo root
  (e.g. grunch_of_giants/grunch_of_giants.epub), which Wiki.js serves.

Resolution

Done 2026-06-27. home.md:175 now reads "View ePub from file location in the
per-book directories (repo root, e.g. grunch_of_giants/grunch_of_giants.epub)"
— no longer references the retired llm-wiki/.
