[eas-cli] Display build logs when --wait flag is set

[AHGIJMKLKKZNPJKQR]

Why

Tracking progress of builds created with eas build requires going to the web UI.
The --wait flag only displays a spinner, which is in contrast to workflows, which display logs and steps as they progress.

How

We use the existing log polling and realtime log centrifugo clients used by workflows to ingest logs as they appear.

• Extracted common logging types and logic from packages/eas-cli/src/commandUtils/workflow/logs into packages/eas-cli/src/commandUtils/logs.
• Updated packages/eas-cli/src/build/build to store the log state and rerender the spinner text when logs change (same as workflows).

Test Plan

CI passes, manual testing with local build of eas cli

Pull request overview

This PR enhances eas build --wait UX by streaming build progress logs into the CLI while waiting, reusing the existing workflow log polling + realtime (Centrifugo) infrastructure and extracting shared log-parsing/state logic into reusable utilities under commandUtils/logs.

Changes:

• Extracted reusable log parsing/formatting/state + realtime watching into packages/eas-cli/src/commandUtils/logs/*.
• Refactored workflow log handling to use the shared logs utilities (LogsWatcher, shared types, shared formatting helpers).
• Updated waitForBuildEndAsync to track log state and re-render spinner text when logs change (including realtime publications), with new build-log formatting helpers.
