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: NVC Feelings and Needs Dialogue
+description: >-
+  The second and third steps of Marshall Rosenberg's Nonviolent
+  Communication — identifying feelings and the underlying needs that drive
+  them. Used to move from observation to connection without blame.

+steps:
+  - headline: Name the feeling
+    description: >-
+      The speaker identifies and names what they feel in response to the
+      observation: "I felt hurt and anxious..." rather than "I felt you
+      were wrong."
+  - headline: Name the need
+    description: >-
+      The speaker identifies the need underlying the feeling, not the
+      other person's behaviour: "...because I have a need for respect and
+      for predictability in our agreements."
+  - headline: Check the need
+    description: >-
+      The listener reflects the need back and asks if they have understood,
+      without agreeing or disagreeing.
+  - headline: Repeat for the other
+    description: >-
+      The other person now identifies their own feelings and needs in the
+      same form, building a shared picture of what each is needing.
+outcome: >-
+  Both parties articulate the needs at stake, moving from positions to the
+  universal needs that can be met in many ways.
+practice: >-
+  Feelings are not judgements — "I feel ignored" is often a thought about
+  the other. "I feel lonely" is a feeling. Needs are universal —
+  "respect," "safety," "contribution" — not strategies.
