refactor(vault): Phase 3 — metadata convergence

- Backfill `created` frontmatter on 266 active notes (git date or mtime)
- Normalize `status` to 4 values: draft/active/done/archived (11 notes)
  - Active/进行中/needs-review → active
  - archive → archived
  - 待执行/conditional → draft
  - 完成/accepted → done
- Declare clipper boundary: 04_Archive/Inbox-Clippings/** exempt from migration
- Update depth rule: max 3 → max 4 levels (new notes only)
- Add metadata-converge.mjs script for reproducibility

 How do you create suspense? I'm asked that question often, and it seems that every writers' symposium has a class with that title. It's an important technical issue, and not just for so-called suspense novels. Every novel needs a narrative engine, a reason for people to keep reading to the end, whatever the subject, style, genre or approach. But it's a bad question. Its very form misleads writers and pushes them onto an unhelpful and overcomplicated track.
 
 Because "How do you create suspense?" has the same interrogatory shape as "How do you bake a cake?" And we all know --- in theory or practice --- how to bake a cake. We need ingredients, and we infer that the better quality those ingredients are, the better quality the cake will be. We know that we have to mix and stir those ingredients, and we're led to believe that the more thoroughly and conscientiously we combine them, the better the cake will taste. We know we have to cook the cake in an oven, and we figure that the more exact the temperature and timing, the better the cake will look.
