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: Nunchi Group Reading
+description: >-
+  A Korean social practice of quickly reading the mood, dynamics, and
+  unspoken context of a room or group before acting or speaking. Nunchi
+  (literally "eye-measure") is a foundational social skill in Korean
+  culture for navigating group harmony.

+steps:
+  - headline: Observe before entering
+    description: >-
+      Before joining a room or conversation, pause and observe: who is
+      present, what is the mood, where is the tension, who holds influence
+      in this moment.
+  - headline: Read the unspoken
+    description: >-
+      Attend to body language, tone, pauses, and what is not being said.
+      Note who defers to whom and where energy gathers or withdraws.
+  - headline: Calibrate your entry
+    description: >-
+      Adjust how and when you enter the interaction — what to say, what to
+      hold, whether to speak at all — based on the reading you have made.
+  - headline: Continue reading throughout
+    description: >-
+      Nunchi is continuous, not a one-time read. Keep observing as the
+      interaction evolves and adjust.
+outcome: >-
+  A person enters and participates in a group in a way that fits its
+  actual dynamics, avoiding missteps and supporting harmony.
+practice: >-
+  Nunchi is not manipulation — it is attention to the collective. The
+  pause before entering is the practice. Speed of reading comes with
+  deliberate attention, not with rushing.
