fix(409): the report check's prefilter no longer depends on compact JSON (#4014)

CI run #517 failed five of the new hook tests, all of them expecting a
request that never went out. The prefilter matched `"name":"…update_task"`
with no space after the colon, which is how Claude Code writes its
transcripts, while the tests wrote theirs with json.dumps defaults
(`"name": "…"`). The hook exited at the prefilter for every test transcript.
The silent-case tests passed for the same wrong reason.

- The prefilter now allows whitespace after the colon. The jq parse behind it
  never depended on formatting.
- The test transcripts are written compact, matching the real file. The
  silent-case tests now reach the turn parse rather than stopping at the
  prefilter.
