feat(mobile): adopt radiance memory monitor, remove Go-side memory logger

[garmr-ulfr]

Summary

Adopts the adaptive mobile memory monitor that now lives in radiance, and removes the redundant Go-side memory logger from the tunnel process.

• Bumps radiance to the build that includes the vpn/memmon adaptive memory monitor (companion PR: feat(vpn): adaptive memory monitor for the mobile VPN daemon radiance#550). On iOS it reclaims proactively under jetsam pressure; on Android it runs observe-only.
• Removes lantern-core/mobile/memory_logger.go and its startMemoryLogger() / stopMemoryLogger() calls in mobile.go. That logger sampled Go-runtime stats via runtime.ReadMemStats (stop-the-world) on a timer in the tunnel process; radiance's monitor now covers memory observation (and reclamation) from inside the same process, without the STW pause.
• Picks up the radiance change to include the memory crash-dump file in issue reports.

Summary by CodeRabbit

• Bug Fixes
  • Reduced background memory logging during mobile tunnel startup and shutdown for a cleaner runtime experience.
  • Removed the periodic memory-reporting process from the mobile IPC flow, helping keep mobile sessions lighter.
• Chores
  • Updated third-party dependencies to newer versions.

Pull request overview

This PR switches mobile tunnel-process memory monitoring/logging responsibility from Lantern’s Go-side periodic runtime.ReadMemStats sampler to Radiance’s adaptive vpn/memmon monitor by bumping the radiance dependency and removing the redundant in-process Go memory logger hooks.

Changes:

• Remove the Go-side tunnel memory logger start/stop calls from StartIPCServer / CloseIPCServer.
• Delete lantern-core/mobile/memory_logger.go (the Go runtime memstats ticker logger).
• Bump github.com/getlantern/radiance to a newer pseudo-version in go.mod/go.sum.

@garmr-ulfr This one looks good to me too. Do you mind fixing the merge conflicts?

[jigar-f]

@garmr-ulfr, it has been tested on iOS, I did not get time to test this in Android, but I think we should test this in Android before merging it in.

@garmr-ulfr This one looks good to me too. Do you mind fixing the merge conflicts?

@atavism, yeah, I can do that. This is still waiting for the companion PR in radiance to be merged.

For future PRs that have a radiance companion, should I keep them as drafts until the companion PR has been merged?
