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: Ikastola Parents' Assembly
+description: >-
+  A Basque practice in which the parents of an ikastola — a Basque-medium
+  cooperative school — govern the school through a general assembly, with
+  each family holding a voice. Ikastolas emerged during the Franco era as
+  grassroots Basque language schools and remain parent-cooperative in
+  governance.

+steps:
+  - headline: Convene all families
+    description: >-
+      The ikastola convenes a general assembly of all families whose
+      children attend. Each family, not each parent, holds a voice in the
+      governance of the school.
+  - headline: Present with full accounts
+    description: >-
+      The governing board presents the school's accounts, educational
+      plan, and staff situation, shared in advance so families arrive
+      informed.
+  - headline: Deliberate on direction
+    description: >-
+      The assembly deliberates on the school's direction — pedagogical
+      choices, Basque-language policy, finances, staffing — with all
+      families able to speak.
+  - headline: Vote by family
+    description: >-
+      The assembly votes on decisions, each family casting one vote. The
+      board is elected or confirmed from among the families.
+  - headline: Mandate the board
+    description: >-
+      The assembly mandates the board to implement the decisions, with the
+      board accountable to the next assembly.
+outcome: >-
+  A Basque-medium school is governed by the families whose children
+  attend, with direction set by assembly and implemented by an
+  accountable board.
+practice: >-
+  The family-as-member structure is what makes an ikastola cooperative,
+  not state. If families disengage and the board self-perpetuates, the
+  form drifts toward ordinary school governance.
