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

+steps:
+  - headline: Map the past
+    description: >-
+      Small mixed groups create a timeline of key events in their own lives,
+      the organisation, and the world over several decades.
+  - headline: Map the present
+    description: >-
+      Groups map current trends and forces affecting the system, noting
+      what they are proud of and what they are sorry about.
+  - headline: Ideal future scenarios
+    description: >-
+      Small groups craft vivid scenarios of the organisation twenty years
+      on, as if they have already happened.
+  - headline: Find common ground
+    description: >-
+      The whole group identifies shared themes and projects that all
+      stakeholders can commit to, setting aside differences.
+  - headline: Action plans
+    description: >-
+      Volunteers form task groups around each common-ground project and plan
+      concrete next steps.
+outcome: >-
+  Diverse stakeholders discover shared ground and commit to projects none
+  could have advanced alone.
+practice: >-
+  Stakeholder diversity is essential — include those with authority,
+  resources, knowledge, and those affected. The "proud/sorry" step often
+  releases energy that agenda control would have suppressed.
