test(baseline): refresh sim-nav baseline to 1156 (issue #5 convergence)

Post-fix state: 37,409 units, diff 1175 -> 1156 (fixed=19 — the
self-site extra-definition family, .ts + component-meta .vue keys).
new=0. The 19 remaining self-site keys (tsc/*.vue) stay in the
baseline: tsgo's getContextualType RPC returns undefined for the
runtime-section props object literal in volar-virtual script-setup
content, so the def path can't reach the contextual member there.
