Static/resource files that aren't models

[jlowin]

Summary

Support for including files that aren't compiled models - static assets, resources, or passthrough files.

Open Questions

• Naming: [[static]], [[resources]], or something else?
• Location: Should they go in models/ dir, or a separate static/ or resources/ dir?
• Ref-ability: Can they be ref()'d by models?
  • If yes: do we track them for staleness? If a static file changes, do consumers recompile?
  • If no: they're just copied to output for downstream consumers
• Manifest tracking: Do they appear in the manifest? Who "owns" their metadata?
• Subgraph behavior: When running colin compile specific.md, are static files included? (Probably yes - "always copy to output")

Context

Mentioned in #22 as [[static]] config in colin.toml, but deferred from initial {% file %} implementation.

Use cases:

• Including a logo or image in output
• Bundling a schema file that models reference
• Copying config templates that don't need compilation
