Fix update_project to use custom GitHub token for cross-org project access

[Copilot]

The update_project handler fails when accessing Projects v2 in organizations different from the repository, throwing "Project not found or not accessible" despite a custom token being configured in safe-outputs.update-project.github-token.

Root cause

The handler's main() function doesn't accept the githubClient parameter passed by the unified handler manager. It always uses the global github object (default GITHUB_TOKEN), which lacks cross-org project permissions.

Other project handlers (create_project, create_project_status_update) already implement this pattern correctly.

Changes

Updated function signatures to accept GitHub client:

• main(config, githubClient) - Factory function
• updateProject(output, temporaryIdMap, githubClient) - Main handler
• resolveProjectV2(projectInfo, projectNumberInt, github) - Project resolver
• listAccessibleProjectsV2(projectInfo, github) - Project lister

Pattern applied:

async function main(config = {}, githubClient = null) {
  const github = githubClient || global.github;
  if (!github) {
    throw new Error("GitHub client required");
  }
  // ... use github for all GraphQL calls
}

All functions fall back to global.github for backward compatibility. Existing tests pass without modification.

Impact

Workflows with custom project tokens now work across organization boundaries:

safe-outputs:
  update-project:
    github-token: ${{ secrets.CROSS_ORG_PROJECT_TOKEN }}
    project: "https://github.com/orgs/other-org/projects/1"
