docs(core): add NX_TUI environment variables documentation (#31619)
This PR added two TUI environment variables to the reference page:
- NX_TUI to enabled/disable
- NX_TUI_AUTO_EXIT to control auto-exit behavior

## Current Behavior

The environment variables documentation does not include the new
Terminal UI (TUI) environment variables `NX_TUI` and `NX_TUI_AUTO_EXIT`
that were recently added to control the interactive terminal interface
for task
execution.

## Expected Behavior

The documentation now includes comprehensive information about the TUI
environment variables:
- `NX_TUI`: Controls whether the Terminal UI is enabled or disabled for
running tasks
- `NX_TUI_AUTO_EXIT`: Controls the auto-exit behavior of the TUI after
tasks complete, supporting boolean values or a number for countdown
seconds

## Related Issue(s)

Fixes #31111

# Environment Variables
The following environment variables are ones that you can set to change the behavior of Nx in different environments.
| Property | Type | Description |
| ------------------------------ | -------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| NX_ADD_PLUGINS | boolean | If set to `false`, Nx will not add plugins to infer tasks. This is `true` by default. Workspaces created before Nx 18 will have this disabled via a migration for backwards compatibility |
| NX_BASE | string | The default base branch to use when calculating the affected projects. Can be overridden on the command line with `--base`. |
| NX_CACHE_DIRECTORY | string | The cache for task outputs is stored in `.nx/cache` by default. Set this variable to use a different directory. |
| NX_CACHE_PROJECT_GRAPH | boolean | If set to `false`, disables the project graph cache. Most useful when developing a plugin that modifies the project graph. |
| NX_DAEMON | boolean | If set to `false`, disables the Nx daemon process. Disable the daemon to print `console.log` statements in plugin code you are developing. |
| NX_DEFAULT_PROJECT | string | The default project used for commands which require a project. e.g. `nx build`, `nx g component`, etc. |
| NX_HEAD | string | The default head branch to use when calculating the affected projects. Can be overridden on the command line with `--head`. |
| NX_PERF_LOGGING | boolean | If set to `true`, will print debug information useful for profiling executors and Nx itself |
| NX_PROFILE | string | Prepend `NX_PROFILE=profile.json` before running targets with Nx to generate a file that be [loaded in Chrome dev tools](/troubleshooting/performance-profiling) to visualize the performance of Nx across multiple processes. |
| NX_WORKSPACE_DATA_DIRECTORY | string | The project graph cache and some other internal nx caches are stored in `.nx/workspace-data` by default. Set this variable to use a different directory. |
| NX_PARALLEL | number | The number of tasks Nx should run in parallel. Overrides any configured value inside nx.json |
| NX_RUNNER | string | The name of task runner from the config to use. Can be overridden on the command line with `--runner`. Not read if `NX_TASKS_RUNNER` is set. |
| NX_SKIP_NX_CACHE | boolean | Rerun the tasks even when the results are available in the cache. |
| NX_DISABLE_NX_CACHE | boolean | Rerun the tasks even when the results are available in the cache. |
| NX_SKIP_REMOTE_CACHE | boolean | Disable all remote caching features. This means that the remote cache will not be read from or written to. Includes Nx Cloud and Powerpack Caches. |
| NX_DISABLE_REMOTE_CACHE | boolean | Disable all remote caching features. This means that the remote cache will not be read from or written to. Includes Nx Cloud and Powerpack Caches. |
| NX_TASKS_RUNNER | string | The name of task runner from the config to use. Can be overridden on the command line with `--runner`. Preferred over `NX_RUNNER`. |
| NX_TASKS_RUNNER_DYNAMIC_OUTPUT | boolean | If set to `false`, will use non-dynamic terminal output strategy (what you see in CI), even when your terminal can support the dynamic version |
| NX_TUI | boolean | If set to `true` or `false`, will enable or disable the Terminal UI (TUI) for running tasks. TUI provides an interactive visual interface for task execution |
| NX_TUI_AUTO_EXIT | boolean/number | Controls whether the TUI automatically exits after tasks finish. If `true`, exits immediately. If `false`, never exits automatically. If a number, shows a countdown for that many seconds before exiting |
| NX_VERBOSE_LOGGING | boolean | If set to `true`, will print debug information useful for troubleshooting |
| NX_DRY_RUN | boolean | If set to `true`, will perform a dry run of the generator. No files will be created and no packages will be installed. |
| NX_INTERACTIVE | boolean | If set to `true`, will allow Nx to prompt you in the terminal to answer some further questions when running generators. |
| NX_GENERATE_QUIET | boolean | If set to `true`, will prevent Nx logging file operations during generate |
| NX_PREFER_TS_NODE | boolean | If set to `true`, Nx will use `ts-node` for local execution of plugins even if `@swc-node/register` is installed. |
| NX_IGNORE_CYCLES | boolean | If set to `true`, Nx will ignore errors created by a task graph circular dependency. Can be overridden on the command line with `--nxIgnoreCycles` |
| NX_BATCH_MODE | boolean | If set to `true`, Nx will run task(s) in batches for executors which support batches. |
| NX_SKIP_LOG_GROUPING | boolean | If set to `true`, Nx will not group command's logs on CI. |
| NX_MIGRATE_CLI_VERSION | string | The version of Nx to use for running the `nx migrate` command. If not set, it defaults to `latest`. |
| NX_LOAD_DOT_ENV_FILES | boolean | If set to 'false', Nx will not load any environment files (e.g. `.local.env`, `.env.local`) |
| NX_NATIVE_FILE_CACHE_DIRECTORY | string | The cache for native `.node` files is stored under a global temp directory by default. Set this variable to use a different directory. This is interpreted as an absolute path. |
| NX_PLUGIN_NO_TIMEOUTS | boolean | If set to `true`, plugin operations will not timeout |
Nx will set the following environment variables so they can be accessible within the process even outside of executors and generators.
| Property | Type | Description |
| ---------------------------- | ------- | --------------------------------------------------------------------------------------------------------------------------------------------------------- |
| NX_TASK_TARGET_PROJECT | string | Set to the project name of the task being run. Use this to tell which project is being run. |
| NX_TASK_TARGET_TARGET | string | Set to the target name of the task being run. Use this to tell which target of the project is being run. |
| NX_TASK_TARGET_CONFIGURATION | string | Set to the configuration name of the task being run. Use this to tell which configuration of the target is being run. |
| NX_GRAPH_CREATION | boolean | Set to `true` during the graph creation process. Use this to have inference plugins run different code during graph creation versus during task execution |
| NX_DRY_RUN | boolean | Set to `true` during dry runs of generators. Use this to avoid side effects during generators. |
| NX_INTERACTIVE | boolean | Set to `false` when running generators with `--interactive=false`. Use this to prevent prompting during generators |
