Three issues fixed:
1. session-init handler: Worker 500 errors caused `throw`, which
hook-command.ts caught and exited with code 2 (blocking error).
This blocked the user's prompt entirely with:
"Hook error: Error: Session initialization failed: 500"
Fix: Log the failure and return SUCCESS so the prompt proceeds.
2. user-message handler: Referenced nonexistent constant
HOOK_EXIT_CODES.USER_MESSAGE_ONLY (undefined). Also used
console.error() for informational output, which Claude Code
may flag as an error. Fix: Use process.stderr.write() and
return HOOK_EXIT_CODES.SUCCESS explicitly.
3. Both handlers threw on HTTP errors from the worker, causing
exit code 2 (blocking). Memory plugin failures should never
prevent users from using Claude Code. All worker HTTP failures
now log and return gracefully.
