docs: drop stale Verbose/Debug invisibility caveat

v1.8.0's hybrid stream capture interleaves Verbose and Debug records
into the chronological pipeline that the AI reads, so the longstanding
"Verbose and Debug streams are NOT visible to you" caveat in the
invoke_expression tool description and the matching Limitations bullet
in README.md no longer apply. Both removed.

 📝 Text File Operations:
 ALWAYS use the specialized cmdlets for text file editing: Show-TextFiles, Add-LinesToFile, Update-LinesInFile, Update-MatchInFile, Remove-LinesFromFile.
 NEVER use Set-Content, [IO.File]::WriteAllText, or other alternatives—even when source code contains $ or backtick characters. Instead, pass content via var1-var4 parameters.
