v1.4.25

Docs-only fix: version-number consistency.

Both README.md (PyPI long-description) and the package-bundled
fpf_thinking_map/README.md were stuck displaying v1.4.4/v1.4.5 while the
shipped package was already at 1.4.24. Fixed the badges/footers in
README.md, fpf_thinking_map/README.md, and ARCHITECTURE.md, and added one
consolidated v1.4.4-v1.4.24 changelog entry (confirmed docs/provenance
only — zero fpf_thinking_map/*.py changes in that range) instead of
leaving a 21-version gap.

No runtime code changes. 22/22 verify checks pass.
