Summary: Pull Request resolved: facebook#39078 Simplifies and hardens behaviour for detecting other processes / dev server instances when running `react-native start`. - New flow: - Exits with error message if port is taken by another process (*no longer suggests next port*). - Exits with info message if port is taken by another instance of this dev server (**unchanged**). - Continues if result unknown. - *(No longer logs dedicated message for another RN server running in a different project root.)* - This now checks if the TCP port is in use before attempting an HTTP fetch. Previous behaviour: [`handlePortUnavailable`](https://github.com/react-native-community/cli/blob/734222118707fff41c71463528e4e0c227b31cc6/packages/cli-tools/src/handlePortUnavailable.ts#L8). This decouples us from some lower-level `react-native-community/cli-tools` utils, which remain reused by the `android` and `ios` commands.

Summary: Pull Request resolved: facebook#39075 Small refactor: reorganise command entry points and types into a consistent pattern. Changelog: [Internal] Differential Revision: https://internalfb.com/D48433284 fbshipit-source-id: 5cc145b474c8c5cbf350cfee1a1b92091afd9b18
Summary: Pull Request resolved: facebook#39078 Simplifies and hardens behaviour for detecting other processes / dev server instances when running `react-native start`. - New flow: - Exits with error message if port is taken by another process (*no longer suggests next port*). - Exits with info message if port is taken by another instance of this dev server (**unchanged**). - Continues if result unknown. - *(No longer logs dedicated message for another RN server running in a different project root.)* - This now checks if the TCP port is in use before attempting an HTTP fetch. Previous behaviour: [`handlePortUnavailable`](https://github.com/react-native-community/cli/blob/734222118707fff41c71463528e4e0c227b31cc6/packages/cli-tools/src/handlePortUnavailable.ts#L8). This decouples us from some lower-level `react-native-community/cli-tools` utils, which remain reused by the `android` and `ios` commands.
