Cryptid Core Co Field Operations

# Cryptid Core Co Field Operations — v0.5.0 "The Field Station Update"

You're not alone out here anymore. Cryptid Core Co has boots on the
ground: staffed Field Stations, a trading post, an assignment board,
company apparel — and the ruins of a station that didn't make it.

## Field Stations
- New generated structure in forest/taiga biomes: fenced compound with
  spruce cabin, supply shed, radio antenna tower, firepit, and paths
- The first station in your world is the PRIMARY station, staffed by
  Agent X and Agent Ropo; later stations get a generic lettered agent
- Agent L's field manuals (lectern + cabin chest) are full of hints
- Abandoned Field Stations (rarer): ruined, mossy, empty — torn journal
  pages and dead batteries tell you what happened. Mostly.

## Agent X — Trading
- Villager-style trade screen, five tiers (Novice to Master), stock
  limits, daily restock
- Currency is Bigfoot evidence ONLY: fur, scat samples, and teeth
- Teeth are premium currency — and now drop only from Elders (60%)

## Agent Ropo — Assignments
- 6 quests in 2 tiers (mid tier unlocks after 2 starter completions)
- Progress reads live from your Field Journal and inventory
- Rewards include batteries, gear, and the 4-piece CCC apparel set
- Sound Library completion grants the Field Researcher advancement
- Quest state survives death and relogging

## Footprint Casting
- Craft Plaster of Paris (3 clay + water bucket = 3)
- Pour onto a footprint, wait 30 seconds (crack overlay + actionbar %)
- Collect a variant-named Footprint Cast (Silver Elder, Brown Kid...)
- Footprints now record the color and age of the Bigfoot that made them
- 20-cast collection log in the journal's new Casts tab

## CCC Field Apparel
- Cap / Jacket / Pants / Boots — quest rewards or craftable with
  leather + CCC Logo Patches
- 3-piece set bonus: Bigfoots flee 2 blocks later, kids come 1 block
  closer, field gear uses 10% less battery

## Field Journal
- Two new tabs: Assignments (live quest progress) and Casts (collection)

## Fixes & Tweaks
- Bigfoots no longer anger at each other from stray rock throws —
  friendly fire causes damage but never group aggression
- All Bigfoots can drop a scat sample on death (25%)
- Tooth removed from the general loot table (Elder-only, in code)
