Fix uncaught exception in project URL resolution fallback path

[Copilot]

Project resolution fails when GitHub API returns transient errors during the fallback query. The resolveProjectV2 function attempts direct lookup via projectV2(number), then falls back to listAccessibleProjectsV2() list search. The fallback path lacked error handling.

Changes

Error handling:

• Wrapped listAccessibleProjectsV2() calls in try-catch blocks
• Added error message indicating both resolution methods failed and suggesting transient API issue

Files modified:

• actions/setup/js/update_project.cjs
• actions/setup/js/create_project_status_update.cjs

Example:

// Before: fallback query throws uncaught exception
const list = await listAccessibleProjectsV2(projectInfo, github);

// After: graceful handling with context
let list;
try {
  list = await listAccessibleProjectsV2(projectInfo, github);
} catch (fallbackError) {
  const who = projectInfo.scope === "orgs" ? `org ${projectInfo.ownerLogin}` : `user ${projectInfo.ownerLogin}`;
  throw new Error(
    `Unable to resolve project #${projectNumberInt} for ${who}. Both direct projectV2 query and fallback projectsV2 list query failed. This may be a transient GitHub API error. Error: ${getErrorMessage(fallbackError)}`
  );
}

Test coverage:

• Added tests for double-failure scenario in both update_project.test.cjs and create_project_status_update.test.cjs
