make the hyperhive reference docs (the repo `docs/` tree, shipped
read-only as the standalone `hyperhive-docs` derivation) available
in-container. When enabled the harness exposes the docs dir to claude
via `claude --add-dir`, so the markdown is readable at
`$HIVE_DOCS_DIR/`, and appends a single pointer sentence to the agent's
system prompt so it knows the docs exist (see
`hive-agent::prompt::render`). Default-on for the root/manager agent
(see `../templates/ruth.nix`), off elsewhere; any agent can flip it from its
`agent.nix`.

Store path of the reference-docs tree exposed at `$HIVE_DOCS_DIR`
when `hyperhive.docs.enable` is set. Defaults to the flake's
`reference-docs` package (the `nix/packages/reference-docs.nix`
build) so a standalone container build from a full checkout
works unchanged. The generated meta flake overrides this with the
narrow `hyperhive-docs` flake input so a doc edit only
re-locks that input instead of rebuilding the container from a
re-hashed `hyperhive` source.
