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

+    description: >-
+      A senior leader calls the indaba, setting the topic and ensuring all
+      affected groups are represented by their recognised spokespeople.
+  - headline: Open statements
+    description: >-
+      Each representative gives an opening position on the matter, heard in
+      full without interruption.
+  - headline: Open deliberation
+    description: >-
+      Discussion proceeds among the representatives, with the convener
+      ensuring that senior voices do not dominate and that dissent is voiced
+      respectfully.
+  - headline: Seek a common position
+    description: >-
+      The convener works toward a position that all can accept, summarising
+      points of agreement and continuing until none object.
+  - headline: Pronounce the outcome
+    description: >-
+      The senior leader pronounces the agreed position, which becomes the
+      binding decision of the indaba.
+outcome: >-
+  A binding communal decision reached through inclusive deliberation, with
+  all represented groups accepting the outcome.
+practice: >-
+  Indaba takes the time it takes; rushing it breaks the form. The convener's
+  skill lies in drawing out quiet voices and synthesising rather than
+  imposing.
