Seed 201: The Tallow Man

## 1.0.0-beta.6
- Build fix: the Simple Voice Chat API is now bundled in `libs/`, so the project builds without downloading it.

## 1.0.0-beta.5
- **The goatman has his own stages**, separate from the Tallow Man's, counted in days (day 1 / 2 / 4 / 6 by default, config section `[goatman]`).
- He shows up on day one now: within about a minute of your first morning he's sat in front of you eating a dead pig. Every new stage opens with its own signature scare.
- Stage 1 daytime events are more frequent (every 3-6 minutes instead of 5-10).
- New commands: `/tallowman goatstage <0-4|auto>`, `/tallowman goatevent`. `/tallowman status` shows both stages.
- The DAY title card shows the goatman's stage; his attack chance follows his own stage.
- Turning the Tallow Man off (`/tallowman stage 0`) no longer stops a goatman stage you set by command.

## 1.0.0-beta.4
- **Simple Voice Chat support** (optional, nothing changes without it):
  - The goatman and the Tallow Man react when you talk near them; shouting makes it worse.
  - Talking in the dark at night brings the next event on sooner.
  - Mimicry: your voice, or another player's, played back slowed down from somewhere you can't see. Only the haunted player hears it. Clips are kept in memory only.
  - "Seed 201" volume slider in the voice chat volume screen.
  - New config section `[voicechat]` (`hearing`, `mimicry`), two new hidden advancements, test command `/tallowman summon goat_mimic`.
