* feat: upgrade diagnostic captures
Collect richer debug and full-logcat bundles with device, backend, hook, portshide, and kernel partition evidence.
Add an explicit kernel image export for maintainer-requested kernel analysis.
* fix: harden diagnostic capture sessions
* fix(lsposed): harden diagnostic export error paths from review
Address correctness findings from a review of the diagnostic-capture upgrade,
all validated on a Pixel 4a via the agent bridge (kernel/debug/logcat exports).
- Kernel image export: wrap exportKernelImagesZip so a zip/IO failure returns
null (and cleans the parts dir) instead of escaping and stranding the export
button disabled; add try/finally at the DiagnosticsScreen call site. Cap the
per-partition dd (skip unknown/oversized partitions, bound with count=) so a
mislabelled or huge partition can't fill /data.
- HookDiagnostics: drive counter deltas off an explicit "baseline captured"
flag instead of baselineCounters.isEmpty(), so a fresh boot with an empty
baseline no longer reports every delta as n/a. Add HookDiagnosticsTest.
- DebugShellSnapshot: raise the 20s snapshot timeout to 60s and preserve+flag a
timeout-truncated section instead of silently dropping it and every later one.
- LogcatRecorder: delete the intermediate raw logcat file after zipping and on
failed start, so repeated captures stop leaking multi-MB files into cache.
- DebugExport: rethrow CancellationException before the generic catch so
navigating away mid-capture cancels cleanly instead of logging a false error.
- DebugCaptureLogging: when the on-disk canonical config is present but
unparseable, refuse the targets-snapshot rebuild (which would reset settings
and clear autoHiddenPackages); fall back to an app-process-only toggle.
- Dashboard: don't warn "ports rules not active" for a module the user disabled
via their manager (new ports_disabled probe, mirrors the activator's guard).
- activator write_atomic: per-process temp name so a boot-time and app-triggered
activation can't corrupt each other's load_status.
- Drop the wasted multi-user pm enumeration from the counter baseline command.
