 * Minimal nested `get`/`set` over string field paths, replacing lodash-es
 * (which pulled a large shared chunk onto unrelated bundles). Supports the
 * dot + bracket notation produced by the form field-path builders, e.g.
 * `title`, `a.b.c`, `items[0].title`, `blocks[id=abc].nested[1].field`.
 *
 * `set` mirrors lodash semantics: it creates intermediate **arrays** when the
 * next path segment is a numeric index and plain **objects** otherwise, and it
 * mutates `object` in place (callers shallow-copy the root first, as before).
 *
 * Deliberately NOT a general lodash replacement — it does not handle quoted
 * keys (`a["b.c"]`), negative indices, or array-path inputs, none of which the
 * form paths ever produce. See nested-path.test.node.ts for the covered cases.
