The Throwing skill shipped with `StrScale`/`DexScale`/`StatTotal`/`StrGain`/`DexGain` all `0` in `skills.json`, so training it never raised Str or Dex — unlike every other weapon skill.
Fills those in by mirroring **Archery** (the Dex-primary ranged analog, which matches Throwing's existing `PrimaryStat: Dex` / `SecondaryStat: Str`): `StrScale 0.025` / `DexScale 0.075`, `StatTotal 10`, `StrGain 0.25` / `DexGain 0.75`.
Data-only change.
### Summary
- Adds the following configurations:
```json
"stats.statMax": "125",
"stats.gainChanceMultiplier": 1.0,
"stats.primaryStatGainChance": 0.75,
"stats.gainDelay": "00:10:00",
"stats.petGainDelay": "00:05:00",
"stats.usePub45StatGain": "False"
```
- Adds Pub 45 stat gain rate for UOML+.
- Reduces the gain delay for legacy stat gain from 15 minutes to 10 minutes.
- Legacy gain no longer requires a gain in skill to gain in a stat.
