- Fix disableBlockStreaming logic in telegram/bot.ts to properly enable
block streaming when telegram.streamMode is 'block' regardless of
blockStreamingDefault setting
- Set minChars default to 1 for Telegram block mode so chunks send
immediately on newlines/sentences instead of waiting for 800 chars
- Skip coalescing for Telegram block mode when not explicitly configured
to reduce chunk batching delays
- Fix newline preference to wait for actual newlines instead of breaking
on any whitespace when buffer is under maxChars
Fixes issue where all Telegram messages were batched into one message
at the end instead of streaming as separate messages during generation.
