fix(intelligence): address PE review — cpp capability table + QueryPlanner profile guard (RAN-155)

- Add CPP_CAPS table (distinct from C# — no ORM, lexical-only auth)
- Add explicit case "cpp","c++" to CapabilityMatrix.tableFor()
- Add "cpp" to asSerializableMap() hardcoded language list
- Remove incorrect CSHARP_CAPS fallback for cpp in ANTLR_LANGUAGES branch
- Add @Profile("serving") to QueryPlanner so it is not instantiated during indexing CLI runs
