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: Daily Stand-Up
+description: >-
+  A short daily team sync in which each member states what they did, what
+  they will do, and what is blocking them. Originating in Scrum and Agile
+  software development, derived partly from Toyota's morning meetings
+  (chorei).

+  - headline: Gather standing
+    description: >-
+      The team gathers standing, at the same time and place each day, around
+      the team's visible work board. Standing signals brevity.
+  - headline: Each person reports
+    description: >-
+      Each member states three things: what I did since last stand-up, what
+      I will do by next stand-up, and what is blocking me.
+  - headline: Park discussions
+    description: >-
+      Any topic requiring more than a minute is "parked" for a separate
+      conversation after the stand-up, with those involved.
+  - headline: Confirm blockers
+    description: >-
+      The facilitator confirms who will address each blocker and by when,
+      and the stand-up closes.
+outcome: >-
+  The team synchronises daily on progress and impediments in under fifteen
+  minutes, with blockers surfaced and owned.
+practice: >-
+  Keep it under fifteen minutes. The stand-up is not problem-solving —
+  park everything that is not a status report. Face each other, not the
+  manager.
