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

+id: jmaa-village-assembly
+title: Jmaa Village Assembly
+description: >-
+  A Moroccan Berber (Amazigh) and Arab practice of village assembly
+  governance, where the men of the village gather to manage water, land,
+  and communal affairs by discussion and consensus. Found across rural
+  Morocco, particularly in the Atlas regions, the jmaa predates and
+  complements state structures.

+steps:
+  - headline: Convene the jmaa
+    description: >-
+      The senior men of the village convene the jmaa at a known meeting
+      place — often the mosque square or a tree. All adult male
+      household heads may attend.
+  - headline: Present the matter
+    description: >-
+      The matter — water allocation, a land dispute, a communal work — is
+      presented. Each affected household speaks through its head.
+  - headline: Deliberate to consensus
+    description: >-
+      The jmaa deliberates until consensus is reached. The senior members
+      guide but do not impose; a decision without consensus does not hold.
+  - headline: Pronounce and record by memory
+    description: >-
+      The decision is pronounced and held in collective memory — often
+      unwritten. The jmaa's authority rests on communal recognition, not
+      on a document.
+  - headline: Enforce collectively
+    description: >-
+      The village collectively enforces the decision. Sanctions for
+      violation are communal — exclusion from water rotation, from
+      communal labour — not imposed by a separate body.
+outcome: >-
+  Village affairs are governed by consensus of household heads, with
+  decisions enforced collectively and held in communal memory.
+practice: >-
+  The jmaa's unwritten character depends on continuity of memory and
+  attendance. Where young men no longer attend, the form ages and
+  weakens. Water allocation is the test — a jmaa that cannot govern
+  water has lost its function.
