Tidal Commission

# Tidal Commission 1.7.0

## New

- Added **Task Lines**, allowing commissions to form progression chains with shared progress tracking.
- Commissions can now require one or more **prerequisite commissions** before becoming available.
- Added two unlock behaviors for follow-up commissions:
  - **Random Pool**: Joins the normal pool and follows existing source, tier, and weight rules.
  - **Priority**: Appears as soon as a regular slot is available, or waits until one opens.
- Added a **Task Line Editor** for creating and managing task lines and their member commissions.
- Added a **Commission Relations** screen for viewing direct prerequisites and follow-ups.
- Added the **Shipyard Restart Plan** example task line, featuring branches, multiple prerequisites, and priority follow-ups.
- `/tc doctor` now detects missing prerequisites, self-dependencies, and dependency cycles.

## Changes & Fixes

- Pending priority commissions are now saved with the player's commission board and persist after rejoining.
- Existing commissions and worlds without task line data remain compatible with 1.7.0.
- Upgrading only adds the example progression links to unmodified built-in shipyard commissions, with backups created beforehand.
- Customized commission files from modpacks will not be overwritten.
- The commission tracking HUD is now disabled by default for new players and after restoring default settings.
- Empty task line JSON files are no longer loaded.
- Added Wiki documentation for task lines, prerequisites, and chained commission progression.
