Summary

Reorganize the OpsQuest documentation around clearer visitor journeys and reduce clutter in the public Zensical site.

Changes

• Group the Zensical navigation into four collapsible sections:
• Play
• How OpsQuest works
• Contribute
• Project
• Consolidate overlapping mission, progression, curriculum, authoring, and roadmap pages.
• Move iteration reports, implemented decisions, and GitHub governance documentation outside the public site.
• Retire the duplicated initial_prompt.md.
• Correct and relocate the learning-journey diagram.
• Clean duplicate generated changelog entries and obsolete Release Please configuration.
• Add make check-docs to validate:
• public navigation ownership and page metadata
• public versus repository-only documentation boundaries
• mission counts and diagram claims
• documented Go requirements
• retired paths and duplicate documentation
• Adopt Go 1.26.0 as the minimum version and Go 1.26.5 as the preferred toolchain.

Compatibility

• Gameplay, profiles, mission identifiers, and sandbox behavior are unchanged.
• Building from source now requires Go 1.26 or newer.
• Some documentation URLs changed as pages were consolidated.
• Historical iteration reports remain available in the repository under project/history/.

Validation

• make check-all
• make docs-check
• make check-docs
• git diff --check
• Strict Zensical build: 16 public pages, no invalid links
• Generated navigation verified as collapsible
