fix(test): assert the default Accept header on the parameters fetch

[vincentchalamon]

The release workflow for v0.16.11 failed on Run tests, so 0.16.11 was tagged but never published to npm.

FAIL src/hydra/parseHydraDocumentation.test.ts > Resource parameters can be retrieved
AssertionError: expected last "spy" call to have been called with [ 'http://localhost/books', …(1) ]

Cause

Two pull requests crossed, twenty seconds apart:

Commit	Merged	Change
57499c5 (#179)	08:17:50	adds the assertion, expecting a plain headers: {}
9738687 (#178)	08:18:10	makes setHeaders() always return a Headers instance carrying the default Accept

Before #178, setHeaders() short-circuited on a falsy options.headers and returned { ...options, headers: {} } with no Accept at all, which is exactly the bug #178 set out to fix. #179 was written against that behaviour.

Each run was green against main as it stood at the time, so neither CI saw the other. main has been red ever since.

Fix

Assert what both changes together are meant to guarantee: the parameters fetch targets the collection, and it carries the default Accept.

Comparing against a Headers instance is not a workable alternative. Headers exposes no enumerable own properties, so the matcher reports "Compared values have no visual difference" while still failing.

Verification

• pnpm test 33/33, pnpm typecheck, pnpm lint and pnpm format:check all clean.
• The assertion is not vacuous: restoring the pre-Fix missing default Accept header when options is an empty object #178 setHeaders() makes it fail with expected null to be 'application/ld+json', so it now guards Fix missing default Accept header when options is an empty object #178's fix rather than just accepting whatever is passed.
