chore: bump version references in Plugin.cs and README

Pre-push grep-verification found four stale v1.4.3 mentions outside the
Slim-Rule history files:

- Plugin.cs schema-gate error message referenced v1.4.3 by name in both
  the comment and the user-facing exception text. Schema stays at v16,
  but the message now points at the current release
- README.md latest-release badge bumped to v1.4.4
- README.md version header bumped to v1.4.4
- README.md Project Status block rewritten for v1.4.4 with the threading
  and IPC safety items as the lead

ROADMAP.md historical references to v1.4.3 are intentional (released-tag,
foundation-reference) and stay.
