chore(cli): temporarily disable Sentry reporting for unclassified errors

Add UNCLASSIFIED code to CliError.Code and use it for catch-all error handlers
in cli.ts, CliContext.ts, and withContext.ts. Generic Error instances that are
not explicitly classified will no longer be reported to Sentry, reducing noise
while we migrate utility packages away from CliError.
