v2026.2.25 — Release factual audit sync

Release-focused factual audit and corrections against released OpenClaw tags.\n\nHighlights:\n- Validated release dates, commit/file stats, module/file inventories, and critical path/symbol references across core docs and analysis files.\n- Added detailed execution plan + evidence report: analysis/release-factual-audit-2026-02-27.md.\n- Corrected release-state wording so docs distinguish latest upstream stable (v2026.2.26) from the latest fully synthesized docs snapshot (v2026.2.25).\n\nThis release preserves release-only documentation policy and improves factual integrity transparency.
