felixxia-oai 486df09a00 Improve Guardian transcript context selection (#38558 )

## What changed

- Replace the single byte limit with token-derived per-entry and separate message and tool transcript budgets.
- Preserve the first and latest user messages, then fill the remaining budgets with recent user, assistant, and tool context while limiting retained non-user entries.
- Truncate oversized entries in the middle without splitting UTF-8 characters, and report the approximate omitted token count.
- Exclude reasoning from the default transcript sources while retaining support when it is explicitly configured.

## Testing

- Cover oversized message and tool-result truncation, user-message retention, separate tool budgeting, configured reasoning, and the resulting Guardian sampling request.
