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: tequio-communal-labour
+title: Tequio Communal Labour
+description: >-
+  A Zapotec and broader Mexican practice of mandatory communal labour for
+  public works, in which each community member contributes days of work
+  rather than money. Originating in Oaxacan Indigenous communities (where
+  it is also called colecta), tequio is recognised in Oaxaca state law.

+steps:
+  - headline: Identify the public work
+    description: >-
+      The comunidad (community assembly) identifies a work needed — a road,
+      a school, a water system, a church repair — that exceeds private
+      capacity.
+  - headline: Assign tequio days
+    description: >-
+      The assembly assigns each adult member a number of tequio days.
+      Contributions are in labour, calibrated to the work needed, not in
+      money.
+  - headline: Work together on set days
+    description: >-
+      On the set days, the community works together, with food provided
+      communally. The work is public, visible, and shared.
+  - headline: Account and complete
+    description: >-
+      The assembly accounts for who served and who did not. Unfulfilled
+      tequio is a serious matter, addressed by the assembly.
+  - headline: Inaugurate together
+    description: >-
+      The completed work is inaugurated with the whole community, marking
+      it as the product of shared labour, not of contract or charity.
+outcome: >-
+  Public works are built through shared labour, binding the community to
+  its infrastructure and to each other.
+practice: >-
+  Tequio is not volunteer — it is obligation. But it is also not coerced
+  by an outside authority; it is the community obliging itself. If some
+  escape it, the form rots.
