fix: logs.file: false in config file ignored when using CLI

[Copilot]

Commander.js's --no-log-file negation option always populates logFile (defaulting to true when not explicitly passed). cliToConfig unconditionally spread file: cli.logFile into the config, so the CLI always sent { logs: { file: true } } to createClient. mergeConfigs then overwrote the config file's { file: false } with the CLI's { file: true }.

Changes

• cli/adapter.ts: Change condition from cli.logFile !== undefined to cli.logFile === false — only inject file: false when --no-log-file is explicitly passed; omit file entirely otherwise, letting config file values take effect
• __tests__/cli.test.ts: Update tests to reflect that default CLI invocations no longer inject file: true into the logs config

// openapi-ts.config.ts
export default {
  logs: { file: false }, // now respected — no crash log written on error
  input: '...',
};

<issue_description>### Description

When setting the following settings in my openapi-config.ts I still get an error logs file on error. It seems this settings is not applied at all.

  logs: {
    // this has no effect
    file: false,
  },

Reproducible example or configuration

See Stackblitz with gibberish url, which will cause an error to be thrown and an error file to be created, even though file is set to false
