liuhao1024 628a414d29 fix(browser): bind CDP binary exemptions to exact method result paths
Second review round: honoring base64Encoded recursively let any nested
dict spoof {"base64Encoded": true, "data": "<secret>"} past the redactor
(Runtime.evaluate returns arbitrary by-value JSON), and two carriers were
missed entirely — Network.streamResourceContent returns unflagged binary
bufferedData, and Network.getRequestPostData's postData was not covered.

Replace the ambient field sets with per-method exact result-path specs:
_CDP_ALWAYS_BINARY_PATHS for declared-binary paths (screenshots, PDFs,
streamResourceContent, beginFrame screenshotData, the nested
CacheStorage.requestCachedResponse.response.body) and
_CDP_FLAGGED_BINARY_PATHS for paths whose carrier object's base64Encoded
sibling gates the exemption (Network/Fetch.getResponseBody body, IO.read
data, getRequestPostData postData). Path suffixes propagate only into the
matching subtree, so base64Encoded is type information solely on trusted
carrier objects — never ambient trust in nested JSON.
