Support files can now either embed inline string content (Inline) or
reference a file path on disk to copy (Copy_from). This enables large
binary-like files such as x-ocaml.js (~16MB) to be managed via
`odoc support-files` without embedding them as OCaml string literals.

The scrollycode extension's x-ocaml script URLs are now configurable
via ODOC_X_OCAML_JS and ODOC_X_OCAML_WORKER environment variables,
and ODOC_X_OCAML_JS_PATH registers the file as a Copy_from support file.

- Add missing 'assets' field to extension_result records (rfc, admonition)
- Remove unused odoc_parser library dependency from dune (msc, mermaid, dot)

Add index.mld files with usage examples for each extension:

- mermaid: Flowcharts, sequence diagrams, state diagrams, etc.
- msc: Message Sequence Charts for protocol documentation
- dot: Graphviz/DOT diagrams for graphs and trees
- admonition: Note, warning, tip, important callout blocks
- rfc: IETF RFC citations with automatic linking

Each extension now has its own documentation page demonstrating
the syntax and showing live rendered examples.
