Let a file resource name a template file in its module's repository

Browse Source 
A file's text may live in files/<name> beside the manifest instead of inline,
so modules can move their files out of module.json (ADR 0349 clause 2, issue
654). The build packs files/ into the module's declared archive and reads each
template back from the packed bytes, proven by the digest, into content: the
manifest the mesh holds, composition and the node-engine stay as they are.
module check, the merge gate and module add read templates from the tree beside
the manifest, so a change to a template alone is judged. A file naming both
template and content, a template outside files/, a missing one, and a held
manifest that still names one are refused by name.
