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: Yangban Council Deliberation
+description: >-
+  A Joseon-dynasty Korean practice of council deliberation among the
+  yangban (scholar-official) class, in which officials discussed policy
+  with reference to Confucian texts and precedent, seeking consensus that
+  balanced royal authority with ministerial judgment. Rooted in Korean
+  Confucian governance from the 14th to 19th centuries.

+steps:
+  - headline: Convene the council
+    description: >-
+      Senior officials (yangban) convene, often at the king's request or on
+      a matter of state. The council deliberates in the presence of
+      Confucian texts and court records.
+  - headline: Cite precedent and text
+    description: >-
+      Each official grounds their position in Confucian classics and in
+      precedent from prior reigns. Argument proceeds by appeal to text and
+      history, not by personal preference alone.
+  - headline: Deliberate to consensus
+    description: >-
+      The council deliberates toward a consensus that balances the king's
+      authority with the officials' collective judgment. Strong dissent
+      is recorded and weighed.
+  - headline: Memorialise the king
+    description: >-
+      The council's consensus, with any dissent, is memorialised to the
+      king as a written memorial. The king may accept, modify, or reject,
+      but the memorial carries the council's weight.
+  - headline: Record for precedent
+    description: >-
+      The deliberation and outcome are recorded in the court annals, so
+      future councils may cite them as precedent.
+outcome: >-
+  Policy is deliberated by scholar-officials with reference to text and
+  precedent, producing a memorial that balances royal authority with
+  ministerial judgment.
+practice: >-
+  The citation of text and precedent is the discipline — it binds
+  argument to shared sources. Without it, deliberation becomes assertion.
+  The record for precedent makes the council's work cumulative.
