Go regexp's $1_ is parsed as a reference to a named group "1_" (underscores are
valid identifier chars), not $1 followed by literal underscore. This dropped the
captured italic content, turning <i>foo</i> into "__" instead of "_foo_".
Use ${1}_ with explicit braces to delimit the group reference, and update the
format_extended_test suite to assert the full round-trip for <i> and <em>.
## Summary
- Extract bare URLs into placeholders before italic conversion to prevent `_text_` inside URLs from being wrapped in `<i>` tags
- Follows existing placeholder pattern (code blocks, inline code, mentions, tables)
- Fixes#784
## Tests
- Bare URL with underscores — no italic tags
- Clean URL without underscores — unchanged
- Markdown link `[text](url_with_underscores)` — href preserved
LLM @mentions are not necessarily Telegram usernames. Auto-wrapping
them in <a href="https://t.me/..."> caused unwanted profile cards.
Keep placeholder protection for italic conversion, restore as plain text.
- Convert @mentions to <a href="https://t.me/username"> in HTML formatter
(Telegram Bot API does NOT auto-link @username in parse_mode: HTML)
- Protect @mentions from italic regex mangling underscored usernames
- Change read_image/read_audio/read_video system prompt from "REQUIRED"
to conditional — model only reads media when relevant to user's question
- Annotate history media tags so model distinguishes group context images
from current-turn images
* feat(telegram): implement robust message splitting and dynamic HTML retry logic
* fix(telegram): fix sendHTML error chain regression and add split depth limit
- Re-check err.Error() in thread-not-found handler instead of stale errStr,
restoring the original chained fallback behavior
- Add maxSplitDepth (5) to prevent unbounded recursion when Telegram
repeatedly rejects split chunks
- Rename misleading test case to reflect actual monolithic fallback behavior
