Subject: feat(newos4): AI paged file reads, durable tool traces, 12k context
 budget, read/tool/verify prompt rules (v4.6.46)

- read_file: offset/limit + JSON {total_chars,truncated,next_offset} (was a hard 8000-char cut with no resume)
- tool results now leave a per-turn trace that is persisted into session context and survives compression
- maxContextTokens 2000 -> 12000; compression keeps 8 exchanges and 400 chars/msg
- system prompt: page big files, prefer grep -n / sed -n / head, re-read + verify after every edit
- verified in the live browser: 30k file pages 0->8000->16000, prompt section present, v4.6.46 served
