Property Sync API v1.0.2

Highlights

This release sharpens synchronization failure handling and completes the
project's portfolio presentation with real dashboard evidence and release
documentation.

Added

• WordPress dashboard, synchronization summary, and activity-log screenshots.
• Release notes for the 1.0.0 and 1.0.1 releases, plus a reusable template.
• Integration coverage for expected item failures, unexpected-error
  propagation, failed-run state, and lock release.

Changed

• Expected property persistence rejections now use a focused domain exception.
• Synchronization logs distinguish invalid payloads, persistence failures, API
  failures, and unexpected programming errors using safe diagnostic context.
• README and architecture documentation better explain the product context,
  engineering choices, and workflow.

Fixed

• Unexpected errors are no longer treated as ordinary per-property failures;
  they stop the run after cleanup so defects remain visible.

Quality

• Updated smoke coverage validates expected and unexpected synchronization
  failures and lock cleanup.

Requirements

• PHP 8.1+
• WordPress 6.5+
• Docker and Docker Compose for local development

Upgrade notes

No data migration or configuration change is required.
