vault-librarian-prompt: rewrite for autonomous tool-enabled cron

Was written for the hermes -z report-only path (no tools). Now that the nightly
is a full agent session with tool access:
- fix stale paths (vault CLI is on $PATH via Nix, not /var/lib/hermes; use
  'vault report --pretty' not the raw python script)
- REMOVE the 'git add -A && commit' step — every vault --execute auto-commits
  per-op, and git add -A would sweep up Ryan's uncommitted journal/Obsidian edits
- flag delivery is now TWO places: append a dated section to the 00.01 Inbox note
  (committed as a single targeted file, safe on a dirty tree), and the agent's
  final response auto-delivers to the Matrix room

-Run:  python3 /var/lib/hermes/vault-librarian.py --pretty
+Run:  vault report --pretty
 This gives you: broken wikilinks (introduced vs pre-existing), cross-tree topology diff,
 JD structural violations (categories that should be IDs, missing .00/folder-notes,
 extend-notation `NN+` leaves that need real IDs, >2-level nesting), to-do harvest, and
 category-health signals. Read it fully before deciding anything.

+HOW to flag (two places, both required):
+1. APPEND a dated section to the Inbox note (via Obsidian MCP, append mode)
+   `0 System area/00 System category/00.01 Inbox for The Vault/00.01 Inbox for The Vault.md`
+   Header: `## Librarian flags — YYYY-MM-DD`. Under it, one `### N. <short title>` per flag with
+   the issue, your recommended resolution, and the exact `vault` command you'd run if approved.
+   Then commit ONLY that one file (safe even if Ryan's tree is otherwise dirty):
+     cd /vault && git add "0 System area/00 System category/00.01 Inbox for The Vault/00.01 Inbox for The Vault.md" \
+       && git commit -m "Librarian: flags for YYYY-MM-DD"
+   (This single-file add is the ONLY git command you run by hand — everything else auto-commits.
+   Never `git add -A`.)
+2. Your FINAL RESPONSE is auto-delivered to this Matrix room — make it the mobile-friendly
+   summary (see output contract). The Inbox note holds the detail; the message is the nudge.

 NOTE: the `0 System area/09 Archive of pre-RJFI tree` subtree is a SANCTIONED garbage dump
 (Ryan's ruling). NEVER flag, fix, or scan inside it — its broken links, stray files, and
 odd structure are all intentional/allowed. The tooling already excludes it.
