Ryan Hamamura 785f11e52d fix: harden SPA navigation with race protection and correctness fixes
- Add navMu to serialize concurrent navigations on the same context
- Replace url.PathEscape with targeted JS string escaper (PathEscape
  mangles full paths and doesn't escape single quotes)
- Collapse syncWithViewTransition into syncView(bool) to remove duplication
- Simplify popstate ready guard in navigate.js
- Preserve URL hash during SPA navigation
