perf: optimize frontend coverage collector (~2x faster)

Three optimizations to reduce wall-clock time:

1. Reduce safeClick timeout from 3000ms to 500ms
   - Elements either exist immediately after navigation or don't exist at all
   - ~75 safeClick calls; if ~30 miss, saves ~75s of dead wait time

2. Replace 18 page.goto() calls with SPA hash navigation
   - After initial page load, the SPA shell is already in the DOM
   - page.goto() reloads the entire page (network round-trip + parse)
   - Hash navigation via location.hash triggers the SPA router instantly
   - Only 3 page.goto() remain: initial load + 2 home page loads after localStorage.clear()

3. Remove redundant final route sweep
   - All 10 routes were already visited during the page-specific sections
   - The sweep just re-navigated to pages that had already been exercised
   - Saves ~2s of redundant navigation

Also:
- Reduce inter-route wait from 200ms to 50ms (SPA router is synchronous)
- Merge utility function + packet filter exercises into single evaluate() call
- Use navHash() helper for consistent hash navigation with 150ms settle time
