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

+title: Gacaca Community Justice
+description: >-
+  A Rwandan practice of community-based justice assemblies that address
+  conflict and, in the post-genocide period, were adapted to try cases of
+  genocide-related crimes. Rooted in traditional Rwandan gacaca (literally
+  "on the grass") gatherings where elders resolved disputes.

+steps:
+  - headline: Convene on the grass
+    description: >-
+      The community gathers outdoors, in the presence of inyangamugayo
+      (persons of integrity) who serve as judges. The gathering is public
+      and community-wide.
+  - headline: Hear the case
+    description: >-
+      The accused and those harmed are both heard, with witnesses and
+      community members free to speak to what they know and saw.
+  - headline: Establish truth
+    description: >-
+      The inyangamugayo and community together establish what happened,
+      drawing on collective memory and witness, aiming for a shared
+      account that the community can accept.
+  - headline: Determine reparation
+    description: >-
+      The assembly determines reparation — confession, apology,
+      restitution, or community service — oriented toward reconciliation
+      and reintegration.
+  - headline: Pronounce and reintegrate
+    description: >-
+      The decision is pronounced in the presence of the community. The goal
+      is reintegration of the offender into community, not isolation.
+outcome: >-
+  Cases are heard and resolved within the community, with truth
+  established collectively and reparation oriented toward reconciliation.
+practice: >-
+  Gacaca is demanding — it asks the community to face its own. It is not a
+  substitute for formal justice where crimes are severe, but a complement
+  rooted in communal accountability.
