RDF STORYTELLERS v0.4d - VOICE VOLUME SLIDER

NEW
===
Mod Settings -> RDF Storytellers now contains an independent Storyteller voice volume slider.

Range:   50% to 200%
Default: 150%
100%:    same SoundDef level as v0.4c

The slider affects only PlayDrone and Mistress commentary voices. It does not alter RimWorld music, UI sounds, weapon sounds, ambient audio, or the text comments.

The volume factor is applied when each voice line plays, so changing the slider takes effect on the next storyteller comment. It is recalculated from the fixed v0.4c baseline instead of multiplying the already-modified value, preventing cumulative volume increases.

VOICES UNCHANGED
================
PlayDrone = Ava Neural / Teasing Playful
Mistress  = Michelle Neural / Soft Commanding

No event weighting, commentary pools, RDF Events integration, or Robotics files were changed.

BUILD
=====
Run Build.bat as with v0.4c. Existing generated neural WAVs may be reused if already present in this extracted build; otherwise the normal generator runs.

EXPECTED LOG LINE
=================
[RDF Storytellers] v0.4d voice-volume commentary installed.
