Subject: [PATCH] fix(gateway): restore short preview truncation for all/new
 tool progress modes (#4935)

The tool_preview_length: 0 (unlimited) config change from e314833c
removed truncation from gateway progress messages in all/new modes.
This caused full terminal commands, code blocks, and file paths to
appear as permanent messages in Telegram -- the old 40-char truncation
was the correct behavior for messaging platforms.

Now:
- all/new modes: always truncate previews to 40 chars (old behavior)
- verbose mode: respects tool_preview_length config for JSON args cap
