fix: keep top-level arrays as arrays in fromSnakeToCamel

[omgate234]

Pull Request

Description:
Patch release 0.3.2. Fixes snake_case to camelCase conversion of API responses
whose payload is a top-level array, then bumps the version and writes the
changelog entry.

fromSnakeToCamel() ran its input through lodash mapKeys, which turns an
array into a plain object keyed "0", "1", and so on. Any response whose
data was an array therefore reached callers as an index-keyed object rather
than an array. Three methods were broken by this:

• Collection.searchTitle() threw (res.data || []).map is not a function
• Video.getThumbnails() threw the same
• Connection.getInvoices() resolved to an object instead of the unknown[]
  its signature declares

Arrays are now mapped element-wise before falling through to the object chain,
which is the guard fromCamelToSnake() already had. Object conversion is
untouched, so nothing else in the response path changes behaviour.

Changes:

• Bugfix: fromSnakeToCamel() keeps a top-level array an array (src/utils/index.ts)
• Regression tests for both converters, top-level arrays, nested arrays,
  empty arrays, arrays of primitives, and the unchanged object path
  (test/regressions.spec.ts)
• Version bump to 0.3.2 in package.json and package-lock.json.
  binaryConfig.version stays at 0.3.1 on purpose, since it pins the
  capture binary artifact and its checksums, not the package
• CHANGELOG.md entry for 0.3.2

Related Issues:
None filed. Found while calling searchTitle() against a live collection.

Testing:

• npm test passes, 23 tests across 2 suites, including the 9 new cases in
  test/regressions.spec.ts
• npm run build runs clean through tsc and tsc-alias
• Re-test any caller that consumes a list-shaped response, since those
  previously received an index-keyed object and downstream code may have been
  written around that shape: Collection.searchTitle(),
  Video.getThumbnails(), Connection.getInvoices()
