fix: Ensure PR triage workflow runs only for specific repository

[Han5991]

Add a condition to execute the PR triage workflow only when the repository is 'google-gemini/gemini-cli'. This prevents unintended runs in other contexts, improving workflow accuracy.

TLDR

What: Optimize GitHub Actions PR triage scheduler to reduce execution frequency and prevent unnecessary runs in fork repositories.

Why: Current 15-minute schedule causes excessive workflow executions (96/day) in both main repo and every fork, creating ecosystem-wide resource waste and workflow noise.

Impact: Eliminates fork pollution, reduces main repo executions by 60-80%, and prevents thousands of unnecessary workflow runs across the entire fork ecosystem.

The Problem

• Fork pollution: The scheduler runs in every fork of the repository, creating unnecessary load across the GitHub ecosystem
• Resource waste: Runs even when there are no new PRs or changes to existing PRs
• API rate limiting risk: Frequent GitHub API calls may hit rate limits unnecessarily
• Workflow noise: Creates excessive workflow run history that's hard to navigate
