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: Gather the brethren
+    description: >-
+      The community gathers, often around a fire, with drummers ready. The
+      elder or leading bredda opens with prayer and sets the theme for
+      reasoning.
+  - headline: Reason together
+    description: >-
+      Participants reason on the theme — sharing analysis, scripture, and
+      lived experience. Each voice is heard; the elder keeps coherence.
+  - headline: Drum and chant
+    description: >-
+      Drumming and chant arise, weaving the reasoning into musical worship.
+      The three nyabinghi drums — bass, funde, and repeater — set the
+      heartbeat.
+  - headline: Close in unity
+    description: >-
+      The session closes when the reasoning and chant have reached their
+      natural end, often with shared food.
+outcome: >-
+  Spiritual and social understanding deepens through combined reasoning and
+  chant; the community is strengthened in shared practice.
+practice: >-
+  Reasoning and chant are not separate — they flow into one another. Honour
+  the elders' role in holding the form.
