Codex+Opus gate (both reproduced): the new mixed-content ordered render path
resolved tool snippets only from the S.messages join (_collectToolResultSnippetsByTid)
and never consulted persistedSnippetByTid (S.session.tool_calls) — so on a
cold/paginated load where the tool_result join misses (#4927 scenario) the inline
card rendered an EMPTY body, AND its tid was added to transparentOrderedToolIds,
suppressing the post-loop derived card that WOULD have recovered via #4927. Build
a transparentPersistedSnippetByTid map from S.session.tool_calls and thread it as a
5th arg to _transparentOrderedToolCall, falling back in both the live and non-live
branches. Also gate the transparent-only scans (S.toolCalls + _collectToolResultSnippetsByTid)
behind isTransparentStream() so non-transparent renders skip the O(messages×parts)
work (Opus perf finding). Redaction (#4926/#4928) was already safe (shared buildToolCard).
+ cold-load persisted-fallback regression test.
