The ablation study was showing inconsistent results for the consteval
optimization (-9% CITM, -1% Twitter) because the ABLATION_NO_CONSTEVAL
guards were missing from two critical code paths:
1. atom() for structs (line 94-102): The consteval optimization for
pre-computing escaped/quoted field names was not being disabled.
2. atom() for enums (line 136-150): The consteval optimization for
pre-computing escaped/quoted enum string values was not being disabled.
With these guards added, the ablation study now correctly shows the full
impact of the consteval optimization:
- CITM: -47% (was -9%)
- Twitter: -38% (was -1%)
This confirms the consteval optimization provides ~2x performance
improvement by pre-computing escaped/quoted strings at compile time
via std::define_static_string and consteval_to_quoted_escaped.
