`tom_som_javascript_v0` — runnable samples

Three runnable samples covering the three access paths to a TomSpecs Spec Object Model document (som_multiplatform_spec_model.md §6). They are hand-authored and preserved across generate_som regeneration (the generator only rewrites the module, meta/, schemas/ and package.json).

Each sample locates the generic runtime through the tomSom.runtimePath recorded in package.json, so it runs against stock node (≥ 18) with no install. Run each from this package directory (tom_som_javascript_v0):

Sample	File	Access path	Run
(a) Typed object-model	a_typed_access.js	The generated typed facade — named accessors, nested-section navigation, the typed SomList collection.	node examples/a_typed_access.js
(b) Generic document	b_generic_document.js	The language-independent generic runtime — string paths into a sparse store, plus JSON / YAML serialization.	node examples/b_generic_document.js
(c) Reflection / meta-data	c_reflection_metadata.js	The value-free reflection surface — load meta/spec_model.meta.json into a SpecModel , enumerate roots/fields, resolve paths to model nodes.	node examples/c_reflection_metadata.js

All three describe the same document shape, and produce output equivalent to their Dart/Python counterparts in tom_som_dart_v0/example/ and tom_som_python_v0/examples/ — illustrating that the typed facade (a) is a thin, type-safe surface over the exact generic store (b), whose schema is described by the reflection model (c).
