Oracle GitHub Integration — read GitHub API in watchdog loop #39

Oracle GitHub Integration

Add collectGitHubStatus() to oracle_watchdog.zig:

• GET /repos/{owner}/{repo}/issues?labels=assign:ralph&state=all&per_page=100
• Count issues by status: labels
• Add GitHubReport struct
• Modify formatReportHTML() to append GitHub section
• Modify watchdogLoop() to call before formatting

Env vars

• GH_TOKEN — GitHub PAT
• GITHUB_OWNER — default gHashTag
• GITHUB_REPO — default trinity

Graceful degradation

If GH_TOKEN not set → skip GitHub section entirely.
