Subject: [PATCH] fix: add recursion guard to prevent 100% CPU when
 STDOUT/STDERR is broken

When the terminal (IDE) is closed without stopping the framework first,
the PTY is destroyed and STDOUT/STDERR become broken file descriptors.
Any subsequent log call via echo/fwrite fails with E_WARNING, the error
handler catches it and calls the logger again, creating a recursive loop
that consumes 100% CPU.

Changes:
- Add static $in_log recursion guard flag to ConsoleLogger
- Wrap log output (echo/fwrite/fflush) with the guard and @ suppression
- Bump version from 1.1.6 to 1.1.7
