// R0.3 — declarative built-in table, made LAZY by #11220.
//
// The object literal below stays as the single place built-ins are declared
// (compile-time duplicate-key safety; the check:known-symbols gate parses this
// literal from source), but its values are now deferred loaders instead of
// eagerly-constructed instances. At module load every ALIAS is registered in
// declaration order; the class import + construction happen on first use via
// loadRegisteredExecutor() and are cached in the same registry a static
// registration would have populated.
//
// Why: importing this barrel previously pulled all ~100 executor modules and
// constructed every instance at boot — ~0.7–1.2s and ~35MB of heap measured on
// top of the minimal set — even for deployments that use a handful of
// providers. Bundlers split the dynamic imports into on-demand chunks.
//
// Contract preserved (pinned by tests/unit/executor-map-golden.test.ts):
//   - keys and their ORDER are byte-stable
//   - each alias still gets its OWN instance (aliases never share)
//   - ctor arguments are unchanged
