Task: Bind ores.scheduler entities to profiles; verify zero-diff regen

Survey every ores.scheduler entity against the profile catalogue, rebind matches, regenerate, and require zero additional diff against the pre-rebind checked-in output.

• Every entity discovered via the scheduler-cpp catalogue entry is surveyed against all Variability Profiles.
• Every matching entity is rebound and regenerated with zero additional diff versus its pre-rebind checked-in output.
• The known service_find_prefix gap on job_definition and the leftover generators/ vs generator/ directory conflict are resolved as part of reaching zero drift.
• No-match entities are recorded with their actual feature values, not silently dropped.
• Full local build and ctest green after regeneration.
