Document native:jump for v3.3 and add dedicated Jump page

[simonhamp]

Summary

• Update the native:jump command reference in the v3 docs to reflect what's actually in NativePHP Mobile v3.3:
  • New options (--ip, --ws-port, --bridge-port, --vite-proxy-port, --no-serve) are marked with a v3.3+ pill
  • Removed retired options (--platform=, ios/i/android/a shorthand, --skip-build) that are no longer in the v3.3 command signature
  • Minor description updates on --http-port and --laravel-port to reflect new defaults / auto-detection behaviour
• Add a dedicated Jump page under The Basics (docs/mobile/3/the-basics/jump) covering:
  • What Jump is and how it works (PHP dev server + artisan serve + WebSocket bridge + Vite HMR proxy)
  • Install links for the Bifrost Jump app on the App Store and Google Play, with a note that Jump v2+ is required for v3.3
  • Network requirements, hot reload, the bridge (and bridge log location)
  • Configuration, multiple network interfaces, BYO server with --no-serve, custom ports
  • A quick reference for when to use Jump vs native:run
• Add a /jump → /docs/mobile/3/the-basics/jump redirect for easy linking from external surfaces

Test plan

• Visit /docs/mobile/3/getting-started/commands#nativejump and confirm the table renders with v3.3+ pills on the new options
• Visit /docs/mobile/3/the-basics/jump and confirm the page renders, appears in the sidebar under The Basics between Overview and Web View, and that the prev/next nav links work
• Confirm /jump redirects to the new docs page
• Confirm both store links open the correct Bifrost Jump app listings
