Subject: [PATCH] fix(tests): raise timeout for tree-sitter WASM cold-start
 tests
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

CI failed on macos-latest with the same commit that had passed twice
before, timing out on the first two tests that pay the one-time
web-tree-sitter Parser.init() cold-start cost — unrelated to the
cache-hit-rate changes in this PR. Bump those two tests past Jest's
default 5000ms so slower/loaded CI runners don't flake.
