Make resolveImages module-private in predownload and align tests to public API

[Copilot]

src/commands/predownload.ts exported resolveImages even though it had no production consumers outside the module. This left an unnecessary public symbol in the command API surface and tests were coupled to an internal helper.

• API surface cleanup

  • Removed the export from resolveImages in src/commands/predownload.ts.
  • Kept usage unchanged inside predownloadCommand, so runtime behavior remains driven by the same internal resolver.

• Test alignment to public contract

  • Updated src/commands/predownload.test.ts to stop importing resolveImages.
  • Derived PredownloadOptions from predownloadCommand and kept assertions focused on command-level behavior (docker pull calls, error paths, and option combinations).

// before
export function resolveImages(options: PredownloadOptions): string[] { ... }
import { resolveImages, predownloadCommand } from './predownload';

// after
function resolveImages(options: PredownloadOptions): string[] { ... }
import { predownloadCommand } from './predownload';

Pull request overview

This PR narrows the predownload command’s API surface by making resolveImages module-private and updating tests to validate behavior through the exported predownloadCommand entrypoint rather than importing an internal helper.

Changes:

• Removed the export from resolveImages in src/commands/predownload.ts.
• Updated src/commands/predownload.test.ts to stop importing resolveImages and derive PredownloadOptions from predownloadCommand.

src/commands/predownload.test.ts:18

• The removal of the dedicated resolveImages test suite drops coverage for several behaviors that are still implemented in predownloadCommand via the (now-private) resolver (e.g., agentImage: 'act', custom registry/tag and digest metadata handling, custom image validation errors, and the api-proxy+cli-proxy combination). Since the intent is to test via the public command API, please add equivalent command-level tests for these cases so regressions in image selection/validation are still caught.
