Subject: [PATCH] test(desktop): add harness integration fixture test for
 kind-9 parser
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Embeds the exact kind-9 content string produced by buzz-acp's
build_sentinel_pending_payload (captured via kind9_content_fixture_structural_invariants
in crates/buzz-acp/src/acp.rs). Verifies that extractPermissionRequest
and isPermissionRequestSentinel accept the bytes the harness actually emits,
closing the harness→desktop wire boundary check.

Two new tests in the 'harness integration fixture' suite:
- test_harness_kind9_content_parses_to_pending_payload
- test_harness_kind9_content_identified_as_sentinel
