Two ComfyUI issues found while testing.
1. Empty output with no error: the Knowledge Base Loader resolved a relative
`path` against ComfyUI's working directory, not this package, so the default
`knowledge_base/` loaded 0 entries (an empty KB is valid) and every concept
became unknown -> empty prompts. Relative paths now resolve against the
package root, and the loader warns when the Knowledge Base is empty.
2. Add a `raw` string output (a JSON dump of the node's data) to the Scene
Analyzer, Scene Validator, Resolver, Category Splitter, and Prompt Builder
nodes, plus a summary `raw` on the Knowledge Base Loader, for inspecting the
pipeline in the graph. Adds a shared to_raw_json helper.
Tests: package-relative path resolution (independent of cwd), empty-KB warning,
raw output content, and updated node metadata/return-arity expectations.

Add nodes/prompt_builder_node.py: PromptBuilderNode, a thin adapter that
delegates to build_prompts (MASTER_SPEC §20, §19).
- Input category_map (CATEGORY_MAP); optional config (COMPILER_CONFIG) defaulting
to Config().
- Emits 21 STRING outputs: one per canonical category (in order) plus the
reserved `negative` and `scene` outputs (always empty in V1). Values are keyed
by output name so wiring stays stable. No compiler logic in the node.
- Registered as SceneCompilerPromptBuilder ("Prompt Builder").
Tests: 21-output metadata, comma formatting + ordering + empty-category strings,
reserved-empty outputs, custom separator via config, and registration.
