feat(core): support providing schema in sync generators

[jogelin]

Summary

Align sync generator invocation with regular generators by providing schema-based options from nx.json and project configuration.

Current Behavior

Currently, sync generators are invoked with only a Tree parameter and do not receive any configuration options from the generator's schema, nx.json, or project configuration:

// Before
export type SyncGenerator = (tree: Tree) => SyncGeneratorResult;

This means sync generators cannot:

• Access generator-specific options defined in their schema
• Use options configured in nx.json via generators configuration
• Use project-level generator defaults
• Apply schema defaults and validations

Expected Behavior

Sync generators should receive combined options from their schema, just like regular generators do, but without command-line arguments (since they're not invoked directly by users).

// After
export type SyncGenerator<T = unknown> = (
  tree: Tree,
  schema: T
) => SyncGeneratorResult | Promise<SyncGeneratorResult>;

Nx Cloud has identified a possible root cause for your failed CI:

The failures in both e2e test tasks are classified as environment_state issues unrelated to the pull request's code changes.

Task: e2e-react:e2e-ci--src/react-rspack.test.ts
This task failed during Playwright browser installation with a "Hash Sum mismatch" error when downloading from Google's Chrome APT repository (dl.google.com). The error shows that the expected and received SHA256 hashes don't match, indicating either a corrupted mirror, a mid-update sync issue, or network corruption. This is a transient external service failure that has no connection to the sync generator schema changes introduced in this PR.

Task: e2e-playwright:e2e-ci--src/playwright.test.ts
This task failed because Playwright tests could not connect to localhost:4200 (NS_ERROR_CONNECTION_REFUSED / Connection refused). The dev server that should have been running was not accessible, which indicates either a timing issue where tests started before the server was ready, a port conflict, or the server failed to start due to resource constraints in the test environment. This is a test infrastructure issue unrelated to the sync generator changes.

The PR modifies how sync generators receive schema-based configuration options by:

• Changing the SyncGenerator type signature to accept a schema parameter
• Updating runSyncGenerator to use combineOptionsForGenerator
• Passing projectsConfigurations and nxJsonConfiguration to all sync generator invocations

None of the failures reference these modified files or functions. The errors are purely environmental - external package repository issues and test server availability problems. These types of failures are common in CI environments and typically resolve on retry or when the external services recover.

A code change would likely not resolve this issue, so no action was taken.
