[Codegen] Hidden folder detection skips all files when workspace path contains hidden directory (e.g. ~/.jenkins/)

[dinisnunes1]

Description

Summary

The codegen's findFilesWithExtension() function incorrectly skips all .mm files when the project workspace is located under a hidden directory (e.g., ~/.jenkins/, ~/.buildkite/, ~/.circleci/). This causes third-party Fabric components to not be registered in RCTThirdPartyComponentsProvider.mm.

Affected Versions

• React Native 0.79.x (confirmed)
• React Native 0.81.x (confirmed - code moved to generateRCTThirdPartyComponents.js)

Root Cause

In generate-artifacts-executor.js, the hidden folder check uses:

if (absolutePath.includes(`${path.sep}.`) && !absolutePath.includes(`${path.sep}.pnpm`)) {                                                                                                                                             
  return null;                                                                                                                                                                                                                         
}

This checks if /. appears anywhere in the entire path, not just the current filename. When the workspace is under ~/.jenkins/workspace/..., every file path contains /.jenkins, triggering the exclusion.

Suggested Fix

Change the check to examine only the current file/folder name:

if (file.startsWith('.') && file !== '.pnpm') {                                                                                                                                                                                        
    return null;                                                                                                                                                                                                                         
  }

This correctly skips hidden folders like .git while allowing files under workspace paths like ~/.jenkins/.

Steps to reproduce

1. Set up a React Native project with New Architecture enabled
2. Add a third-party Fabric component (e.g., @shopify/flash-list)
3. Build from a workspace under a hidden directory (e.g., ~/.jenkins/workspace/project/)
4. Run pod install and check the generated RCTThirdPartyComponentsProvider.mm

Expected: File contains component mappings (e.g., AutoLayoutView, CellContainer)
Actual: File contains no third-party component mappings

N/A (it's a build issue and using the template will use Github Actions and will not reproduce the issue - it happen only on CI tools with their default installation path at ~/.jenkins or ~/.buildkite or ~/.circleci)
