Commit Message

[loadgen] Remove the workload distribution (#688)

#### Type of change

- Improvement
 
#### Description

- The load generator's `Distribution` descriptor supported five variants
(`const`, `uniform`, `normal`, `bernoulli`, `discrete`), but only
`const` was ever used. Load generation holds each parameter at a fixed
value so results are deterministic and comparable across runs, so the
unused variants only added config surface, sample-YAML documentation,
generator types, and tests with no realized benefit. This collapses
`Distribution` down to plain constant values.

- Delete `distributions.go` and the orphaned
`Const`/`FloatToInt`/`FloatToPositiveInt`/`FloatToBoolean` generators;
`MultiGenerator.Count` is now a plain `int`.
- Replace the `*Distribution` profile fields with plain scalars:
read/read-write/blind-write counts and query size become `uint32`, the
minimal invalid-keys portion becomes `Probability`, and the dependency
gap becomes `uint64` (min 1).
- Keep per-transaction conflict injection (invalid signatures and
dependency probability) via a small `bernoulliGenerator` (`rnd.Float64()
< p`) with identical semantics to the previous Bernoulli-based path.
- Update the sample `loadgen.yaml` documentation and the affected tests.
