fix: rename seed files and IDs to match cleaned titles

All 100 seed YAML files now have:
- Filenames that match their id field
- IDs that are slugs of their titles
- No cultural identifiers in titles or IDs

70 files renamed. e.g. quaker-meeting-for-worship.yaml -> meeting-for-worship.yaml,
moroccan-jmaa-village.yaml -> jmaa-village-assembly.yaml,
japanese-hansei.yaml -> hansei-reflection.yaml

+  northern Japan (Hokkaido) and Sakhalin.

+steps:
+  - headline: Recognise the obligation
+    description: >-
+      When a household within the utari (kin network) faces a birth, death,
+      harvest, or hardship, the network recognises an obligation to assist.
+  - headline: Gather helpers
+    description: >-
+      A senior member calls the utari together, naming the need and the
+      households who will contribute labour, food, or presence.
+  - headline: Work and share food
+    description: >-
+      The network gathers, works the task together, and shares a meal. The
+      host household provides; helpers bring what they can.
+  - headline: Reciprocate in turn
+    description: >-
+      Each contributing household knows its turn will come. The obligation is
+      ongoing, not transactional.
+outcome: >-
+  No household faces major life events alone; the utari binds the community
+  through acknowledged mutual dependence.
+practice: >-
+  Utari is not charity — it is kinship obligation. Honour reciprocity across
+  time; do not extract help without offering it when called.
