charts, data-tables and resources-list had no <profile>.meta.json at all, so the manifest carried
no label for them and the Studio rail humanized the folder name: "Charts", "Data Tables",
"Resources List". Those say what the file is called, not what the page answers.
Each now has a meta with a label and its stage:
charts Gospel Resources -- where the gap is, by language
data-tables Gospel Resources -- every resource and every gap, in tables
resources-list Gospel Resources -- what each people group has
All three declare "stage": "experimental" EXPLICITLY, which is what they already were. A meta-less
profile and a meta without a stage key both default to experimental in profile-meta.mjs, so the
value would otherwise rest on that default -- and these three sit in a bundle whose stage reads
production through gospel-dashboard, so a later change to the default would silently promote them.
Measured after the change: the three stay experimental, gospel-dashboard stays production, and
bundleStage still returns production.
Type is deliberately not declared. generate-tree resolves the composition tier from meta.json
`type`, not from whether the file exists, so omitting it leaves all three inferred `single`
exactly as before. Nothing in the manifest moves except the three labels and three stage values
that already held.
