[Feature] Android Code Review Skill

Proposed Skill

Currently, there isn't a seamless automated hook or workflow integration to trigger the Android Code Review Skill during local prep (pre-PR) or automatically upon opening a Pull Request.

I want to be able to run this skill to get actionable code feedback before opening a PR (e.g., via a local CLI/Git hook) or automatically when a PR is opened (e.g., via GitHub Actions / CI pipeline), ensuring potential Android-specific issues are caught early.

Additional Context

1. Pre-PR / Local Run: Ability to trigger the skill locally against modified/staged Kotlin or Java code before committing/pushing.
2. On PR Creation: Automated trigger (such as a GitHub Action workflow) that runs the skill on newly opened PRs and posts actionable review comments/feedback directly on the diff.
