fix stale rendered tool/param names in markdown render strings

Final review caught three salvage artifacts in MODEL-FACING rendered text (the design
doc was right; the render strings were stale): the elided-turns marker pointed at
find_session_transcripts(transcript_ref) for an outline (find takes no ref — that's
read format=outline); the header said format=transcript_jsonl (now jsonl); the
hard-cap note said full_result_for (now expand_turn). Tests asserting the old strings
updated. #1 fired on the default read of any long session.
