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: Folk High School Life Phrase Sharing
+description: >-
+  A practice from the Scandinavian folk high school tradition where students
+  share a personal "life phrase" — a statement of where they are in life —
+  at the opening of a term. Folk high schools, originating in 19th-century
+  Denmark and spread across the Nordic countries, emphasise dialogue and
+  civic formation.

+steps:
+  - headline: Each student prepares
+    description: >-
+      Before the term opens, each student reflects on and writes a short
+      phrase describing where they are in life — their current question or
+      longing.
+  - headline: Share in circle
+    description: >-
+      In an opening circle, each student reads their life phrase aloud. The
+      group listens without comment or question.
+  - headline: Hold the phrases
+    description: >-
+      The phrases are held by the group as a portrait of where the cohort
+      is. They may be revisited at term's end to notice change.
+outcome: >-
+  The cohort begins with mutual awareness of each person's life context,
+  building the trust that folk pedagogy depends on.
+practice: >-
+  Resist discussion after each phrase — the form is witness, not dialogue.
+  The phrases become a reference point; returning to them at term's end is
+  powerful.
