Prepare Crop Control Override 2.1.0.0 Alpha 16.7

[SimGamerJen]

Summary

Stages the complete, tested Crop Control Override 2.1.0.0 Alpha 16.7 source and documentation for an experimental GitHub pre-release.

Included

• Save-specific visual crop-calendar editing
• Dynamic base-game and custom-map crop discovery
• Whole-lifecycle shifts and custom planting/harvesting windows
• Draft Preview, Cancel, Apply and Restore workflows
• Joined calendar bars, month dividers and fixed legend
• NPC map regeneration and contract-board rebuilding
• Updated English, German and French localisation
• Updated README and Alpha 16.7 release notes
• Revised Hyper138 contributor acknowledgement

Current limitation

Existing player and NPC field growth states are reported when a calendar changes but are deliberately not remapped in Alpha 16.7. Field-state reconciliation is planned for a later experimental build.

Rebuild verification

The release branch was rebuilt from the verified Alpha 16.7 package objects rather than from the stable main source. A clean checkout of the branch confirms:

• modDesc.xml version: 2.1.0.0
• Author: SimGamerJen
• Runtime version: 2.1.0.0-alpha.16.7
• scripts/CropCalendarManager.lua present
• Alpha 16.7 contributor acknowledgement present
• Temporary recovery workflow removed
• Temporary .release payload directory removed

Validation completed on the packaged build

• Lua syntax checks
• XML parsing
• GUI and localisation ID checks
• ZIP integrity testing
• Live in-game testing of calendar shifts, custom windows, draft cancellation, restoration, field-impact reporting and contract rebuilding

This PR remains draft and unmerged. It should not be merged merely to publish the pre-release; the release tag should target the verified release-branch head after final review.
