chore: prune obsolete project documentation files and consolidate sta…

[ABEEGOLD]

Closes #368

Summary

Consolidate 9 overlapping and stale "project complete / ready" summary documents at the repo root into a single living PROJECT_STATUS.md file, delete the obsolete files, and update references across existing repository documentation.

Fixes #368.

Motivation & Context

The repository root contained 9 separate project completion/status summary files created at different points in time (ALL_TASKS_COMPLETION_SUMMARY.md, FINAL_PROJECT_SUMMARY.md, FINAL_STATUS.md, IMPLEMENTATION_COMPLETE.md, IMPLEMENTATION_SUMMARY.md, DEPLOYMENT_READY_SUMMARY.md, FINAL_DEPLOYMENT_UPDATE.md, FINAL_VERIFICATION.md, and PUSH_SUMMARY.md).

Several of these documents falsely claimed 100% completion or deployment readiness despite build compilation errors present in the crate. Consolidating these into a single living status document (PROJECT_STATUS.md) ensures that contributors, reviewers, and indexers have a single, accurate source of truth for contract capabilities and active build status.

Changes Made

1. Living Status Document

• Created PROJECT_STATUS.md: Details implemented feature modules, contract architecture, required next steps, and explicitly documents current build state (cargo test failure in dongle-smartcontract/src/utils.rs).

2. File Cleanup

• Deleted 9 Obsolete Summary Docs:
  • ALL_TASKS_COMPLETION_SUMMARY.md
  • FINAL_PROJECT_SUMMARY.md
  • FINAL_STATUS.md
  • IMPLEMENTATION_COMPLETE.md
  • IMPLEMENTATION_SUMMARY.md
  • DEPLOYMENT_READY_SUMMARY.md
  • FINAL_DEPLOYMENT_UPDATE.md
  • FINAL_VERIFICATION.md
  • PUSH_SUMMARY.md

3. Documentation References Updated

• README.md: Added a link to PROJECT_STATUS.md in the overview section.
• Updated links and references in ARCHIVE_FEATURE_INDEX.md, CODE_CHANGES_REFERENCE.md, FEATURES_SUMMARY.md, LOCAL_TEST_EXECUTION_GUIDE.md, README_ARCHIVE_FEATURE.md, and VERIFICATION_CHECKLIST.md.

Verification

• Deletion Check: Confirmed all 9 stale files were removed from repo root.
• Reference Grep: Verified via global regex search that zero broken references to the deleted summary files remain across all .md files.
• Git Status: Clean working tree on branch Consolidate-9-overlapping-project-complete-ready-summary-docs-at-repo-root.

Checklist

• Consolidate overlapping status files into single living document (PROJECT_STATUS.md)
• Delete stale/misleading completion docs
• Update links in existing documentation files
• Verify zero broken document references remain
