* feat: Add OCIMYSQLDATABASE entity definition (staging)

Add OCI MySQL Database entity definition with:
- Entity definition with synthesis rules
- Golden metrics (CPU utilization, active connections, statement latency, memory utilization)
- Summary metrics
- Test data
- Using .stg.yml suffix (staging only)

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* fix: rename Metric.json to Metric.stg.json for staging-only definition

Staging-only definitions (using .stg.yml suffix) require test files to
also use the staging suffix (.stg.json). The CI validator rejects
non-staging files in staging-only definitions.
