[Bug] oclite: Debug logging written to stdout instead of stderr

[randomm]

Problem

Debug log lines like [DEBUG] handleCustomCommand: Received chunk type="text" are written to stdout, interleaving with actual response text:

traits[DEBUG] handleCustomCommand: Received chunk type="text"
**:[DEBUG] handleCustomCommand: Received chunk type="text"
 Database[DEBUG] handleCustomCommand: Received chunk type="text"

Every single text chunk gets a debug line, making the output unreadable.

Root Cause

console.error() or console.log() debug statements in the custom command handler are writing to stdout. They should either:

1. Be removed entirely (preferred — debug logging was added during development)
2. Or use process.stderr.write() exclusively

Expected

No debug output visible during normal operation. Response text streams cleanly.

Completed in commit 14244a5. All stderr.write debug logging removed.
