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: Settle into silence
+    description: >-
+      The meeting begins as participants enter and settle into silence
+      without a leader or liturgy. There is no programme or hymn.
+  - headline: Speak as led
+    description: >-
+      Anyone who feels moved by the Spirit may rise and speak a brief
+      message. After each message, the group returns to silence.
+  - headline: Hold the silence
+    description: >-
+      The meeting may pass entirely in silence, or include several messages.
+      Silence is not emptiness but worship.
+  - headline: Close with handshakes
+    description: >-
+      After about an hour, an elder turns to a neighbour and shakes hands,
+      signalling the close. All exchange handshakes.
+outcome: >-
+  Participants experience communal worship through silence and any spoken
+  ministry that arises, without liturgy or hierarchy.
+practice: >-
+  The discipline is the silence — do not fill it. If you speak, stand and
+  speak briefly; do not debate or reply to another's message. Let the
+  silence hold what is said.
