Kudzu 0.10.2 - Shared-layout navigation

Kudzu 0.10.2 preserves layout-owned workspace state across explicit list/detail navigation while route-owned drafts reset on exit, revisit, and direct document load. The release adds no compiler pass or browser runtime concept; /help remains a zero-JavaScript native-navigation target.\n\nValidation: 273/273 tests, required-Chrome application journey, Node current/22 CI, package smoke, and a 2.3 ms median across seven fresh-profile navigation samples.\n\nUpgrade: npm install @kudzujs/core@^0.10.2
