Apply agent config audit fixes (PRI-14)

Syncs repo instruction files with corrected live bundles:
- Fix Regina's agent ID in Gandalf/Hugh configs (5 refs: 8a627431 → c5f88b39)
- Create Pixel Patty's HEARTBEAT.md and SOUL.md (was missing entirely)
- Fix Karen's PRODUCT-CONTEXT.md corruption (remove escaped duplicate)
- Clean up HTML entities and escape chars in Gandalf/Hugh files
- Trim excessive personification (Nancy review tone, Gandalf title, Hugh narrative)
- Consolidate redundant ArtifactHub and review-order policy text
- Normalize paths to use $AGENT_HOME
