First dispatch on the empty template failed at Chroma collection
creation because PRODUCT_NAME was the literal string "<product>"
(YAML doesn't expand placeholders), and Chroma rejects collection
names containing characters outside [a-zA-Z0-9._-]:
chromadb.errors.InvalidArgumentError: Validation error: name:
Expected a name containing 3-512 characters from [a-zA-Z0-9._-],
starting and ending with a character in [a-zA-Z0-9]. Got:
<product>_docs
Same fix as the IMAGE env: derive from the repo name dynamically
via ${{ github.event.repository.name }}. Cloners can still override
explicitly, but a fresh clone now runs the index-rebuild step
cleanly out of the box.
Verified by re-dispatch — should fail next at docker login (placeholder
REGISTRY_PUSH hostname), which is the next-expected fail point and a
real per-deployment config the cloner has to fill in.
