Depends on langchain-ai#4561. Deep Agents Code now displays both legacy and current `read_file` line gutters without dropping tab-based source indentation. --- Deep Agents Code compacts `read_file` line-number gutters before displaying tool output. The SDK change in langchain-ai#4561 replaces the ambiguous tab separator with two spaces, but the TUI parser currently recognizes only the legacy format. Teach the parser to recognize both formats while consuming only the gutter separator. This preserves tabs that belong to source indentation and keeps compatibility with older string backends that still emit `cat -n`-style output.

Depends on #4561.
Deep Agents Code now displays both legacy and current
read_fileline gutters without dropping tab-based source indentation.Deep Agents Code compacts
read_fileline-number gutters before displaying tool output. The SDK change in #4561 replaces the ambiguous tab separator with two spaces, but the TUI parser currently recognizes only the legacy format.Teach the parser to recognize both formats while consuming only the gutter separator. This preserves tabs that belong to source indentation and keeps compatibility with older string backends that still emit
cat -n-style output.
