Provide repository architecture and build workflow analysis for Sketchware Pro

[Copilot]

This issue requested a project-level analysis rather than a feature/code fix. This PR delivers a concise technical map of the repository so contributors can navigate modules, ownership boundaries, and build flow quickly.

• Problem scope

  • Clarified that the request is analytical (分析项目): document structure, stack, and execution flow of the existing codebase.

• Architecture map delivered

  • Identified core compilation/codegen pipeline in pro.sketchware.core (e.g., ProjectBuilder, manifest/activity/layout/code generators).
  • Highlighted dominant design patterns (registry + manager-heavy architecture) and where extension logic lives (mod/*).

• Module and entry-point breakdown

  • Documented responsibilities of :app vs :resolver.
  • Mapped app bootstrap and UI entry path (SketchApplication → MainActivity + manifest declarations).

• Build/CI contract surfaced

  • Captured canonical build path from repo config and workflow (./gradlew assembleDebug, JDK 17, AGP 8.12.0, Gradle 8.13).
  • Noted external dependency resolution constraint in the current sandbox environment (network-bound), to distinguish infra limits from code-level faults.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
