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

+description: >-
+  The fourth step of Marshall Rosenberg's Nonviolent Communication — making
+  a clear, actionable request rather than a demand. Used after observation,
+  feelings, and needs have been shared.

+steps:
+  - headline: Form a concrete request
+    description: >-
+      The speaker makes a specific, doable request: "Would you be willing
+      to check in with me before changing our shared deadline?" rather than
+      "I want you to be more considerate."
+  - headline: Phrase as a question
+    description: >-
+      The request is phrased as a question the other can answer with no,
+      without punishment. A request is not a demand.
+  - headline: Receive the answer
+    description: >-
+      The speaker receives the answer — yes, no, or counter — without
+      withdrawing empathy or imposing consequence. A "no" is information
+      about the other's needs, not a rejection.
+  - headline: Continue the dialogue
+    description: >-
+      If the answer is no, the speaker returns to the other's feelings and
+      needs, exploring what need the "no" is meeting.
+outcome: >-
+  A clear request is made that the other can freely accept or refuse,
+  keeping the dialogue in connection rather than coercion.
+practice: >-
+  If a "no" leads to punishment or guilt, the request was a demand. Test
+  yourself: would you still respect a "no"? If not, you are not yet making
+  a request.
