TFC Depth Prospecting

TFC Depth Prospecting expands TerraFirmaCraft prospecting into a slower, more deliberate surveying workflow. Instead of relying on a single random prospecting result, you can gather broader mineral summaries, perform time-consuming deep surveys, and generate readable survey reports for planning your mining operations.

### Features
- Multi-mineral normal prospecting: supported prospecting tools can show all detected minerals in the scanned area instead of only one random result.
- Configurable result display: prospecting summaries and survey reports can use exact counts or approximate amount categories.
- Deep surveying: sneak-right-click with a supported prospecting tool while holding a Charcoal Pencil in your offhand and carrying paper to begin a deep survey.
- Survey reports: completed deep surveys generate an in-game Survey Report that opens as a readable book and lists the minerals found in the scanned volume.
- Charcoal Pencil marking: mark blocks in the world and use the calculated center-point overlay to help map ore circles or survey reference points.
- Optional report highlighting: servers can allow held Survey Reports to highlight matching minerals on the client.
- Precision Prospecting compatibility: built-in support for Precision Prospecting tools when that mod is installed.
- Data-driven survey adapters: modpack authors can add support for additional survey tools through datapacks.

### How It Works
- Craft a Charcoal Pencil from charcoal and a knife.
- Use a supported prospecting tool normally to get a broader mineral summary.
- For deep surveying, hold the Charcoal Pencil in your offhand, keep paper in your inventory, then sneak-right-click a block with your prospecting tool.
- The survey consumes durability, paper, and time. Once it finishes, you receive a Survey Report.

### Requirements
- Minecraft 1.21.1
- NeoForge 21.1.x
- TerraFirmaCraft 4.1.0+
- Optional: Precision Prospecting 2.0+

Notes
- Deep surveying is disabled by default. Enable it in `tfcdepthprospecting-server.toml` if you want the feature active.
- Report location details and held-report highlighting are configurable server options.

TFC Depth Prospecting 是一个面向 TerraFirmaCraft 的勘探扩展模组。它把原本偏一次性的矿脉勘探，扩展成更完整的“地质调查”流程，让找矿不再只是碰运气，而是更有计划、更有沉浸感。

### 主要内容
- 普通勘探会显示扫描范围内的多种矿物，不再只给出单一结果。
- 勘探结果和调查报告都可以显示精确数量，或使用“大概储量”分级。
- 新增深度勘探玩法：主手使用勘探工具，副手拿炭笔，背包里带纸，潜行右键即可开始调查。
- 深度勘探会消耗工具耐久、炭笔耐久和纸张，并在完成后生成可阅读的调查报告。
- 调查报告会以书本界面打开，方便整理和查看矿物分布结果。
- 炭笔可以在方块上做标记，并显示推算出的中心点，方便圈定矿区或辅助定位。
- 可选兼容 Precision Prospecting。
- 支持通过数据包扩展更多勘探工具，适合整合包作者使用。

### 依赖
- Minecraft 1.21.1
- NeoForge 21.1.x
- TerraFirmaCraft 4.1.0+
- 可选：Precision Prospecting 2.0+

### 注意
- 深度勘探默认是关闭的，需要在 `tfcdepthprospecting-server.toml` 中手动启用。
- 报告坐标信息和手持报告高亮功能也都可以通过配置控制。
