Pull Request Overview

Adds support for a live-reload watcher in the CyPrompt flow when developing against a local cy-prompt path.

• Refactors ensureCyPromptBundle to always compute its own bundlePath and remove the old local-copy branch
• Introduces a chokidar watcher in CyPromptLifecycleManager guarded by CYPRESS_LOCAL_CY_PROMPT_PATH
• Updates unit tests to cover both remote bundle and local watcher scenarios

packages/server/lib/cloud/cy-prompt/CyPromptLifecycleManager.ts:19

• [nitpick] The name hashLoadingMap is ambiguous; consider renaming it to hashLoadingPromises or loadingPromiseByHash for clearer intent.

private static hashLoadingMap: Map<string, Promise<void>> = new Map()

packages/server/test/unit/cloud/cy-prompt/CyPromptLifecycleManager_spec.ts:100

• Consider adding a test that calls initializeCyPromptManager multiple times with the same cyPromptHash to verify that ensureCyPromptBundle is only invoked once and that subsequent calls reuse the cached promise.

// Add tests for cached bundle loading behavior

packages/server/lib/cloud/cy-prompt/ensure_cy_prompt_bundle.ts:14

• The code uses path.join but the path module is not imported. Add import path from 'path' at the top of the file to avoid a ReferenceError.

const bundlePath = path.join(cyPromptPath, 'bundle.tar')
