Summary

This PR brings the branch's cumulative ScreenKit updates through Android v2.2.0 (versionCode 11) into main.

Streaming and iOS

• Add Android RTMP/RTMPS Go Live with audio controls, live status, resource cleanup, and startup fixes.
• Vendor the RootEncoder transport with license notices; harden certificate/SAN validation, stream-key privacy, and AVC packetization.
• Add a native iOS 17+ companion with recording, import/trim/PNG/GIF tools and a ReplayKit broadcasting extension, plus XcodeGen configuration and CI.

Capture and automation

• Add floating Long SS and settled multi-frame capture with bounded, approximate stitching.
• Replace synthetic magnifier visuals with a consented live pixel feed; remove Zoom from the floating menu as requested.
• Support custom 0.2–3600-second scroll intervals, first-item delay, and Hold/Resume/Next.
• Add opt-in experimental visible-control Smart playback/ad handling, including Skip ad buttons and conservative mid-roll/ad-pod resumption timing.

Optional network ad filtering

• Add an explicitly consented DNS-only local VPN that starts with floating controls and stops when they close; Turn off disables automatic startup.
• Use a small bundled domain blocklist and encrypted upstream DNS to Cloudflare, with no saved query history.
• Add bounded UDP/TCP DNS handling, flow control/retransmission tests, and fail-open shutdown after repeated resolver failures.
• Avoid automatically replacing other VPNs; document strict Private DNS and Android Always-on/lockdown incompatibility.

Validation

• Final Android build and unit-test tasks passed at 643e3428a72de159fdae1f4aae7693c242ced519: https://github.com/sharthak18/screenkit/actions/runs/41047051127
• Includes 18 new DNS/packet regression tests and additional automation/streaming tests.
• Earlier iOS CI passed core tests plus unsigned device/simulator compilation: https://github.com/sharthak18/screenkit/actions/runs/40572894152
• Working tree matches the pushed branch; no additional source changes made while opening this PR.

Limitations / review notes

• Physical-device networking, social-app behavior, and live platform streaming still need validation; checklists are in docs/ and ios/TESTING.md.
• Smart playback and DNS filtering are experimental, not universal ad blocking or unskippable-ad bypasses. Same-host video ads and app-specific encrypted DNS can evade filtering.
• Long screenshot stitching is approximate on sticky/dynamic layouts; protected screen content may remain black.
• Android APKs are debug-signed. iOS requires Apple signing; no installable signed IPA is included.
• Review foreground-service/VPN consent and privacy disclosures before any store submission. No store publishing or ad monetization integration is part of this PR.
