**chore(archive): remove outdated documentation and summaries**

- Deleted the following obsolete files:
  - `CHANGES.md`, `changes-summary.md`, `CHANGES_SUMMARY.md`: Contained redundant or outdated change logs and implementation summaries.
  - `COMPATIBILITY.md`: Detailed compatibility behavior no longer relevant after environment detection updates.
  - `fix-documentation.md`: Addressed a resolved issue regarding `process.memoryUsage` errors in testing.
  - `DIMENSION_MISMATCH_SUMMARY.md`: Provided a legacy summary of resolved embedding dimension mismatch issues.
  - `demo.md`: Documented an outdated demo process for testing Brainy features.
  - `CONCURRENCY_IMPLEMENTATION_SUMMARY.md`: Summarized already-documented concurrency features.
  - `IMPLEMENTATION_SUMMARY.md`: Detailed an obsolete implementation of optional model bundling.

- Purpose:
  - Streamline and declutter archive by removing redundant or outdated documentation.
  - Align repository with current feature set and documentation standards.
