iOS memgraph leaks

Pair with ios-debugger-agent to build and drive the flow. Scripts live in this skill's scripts/ (resolve the skill folder, not the app repo's cwd). Store captures in a temp folder.

• Capture: scripts/capture_sim_memgraph.sh --udid <sim> --bundle-id <id> --out-dir <dir>.
• Summarize: scripts/summarize_memgraph_leaks.py <file.memgraph> --trace-limit 5 --out <file.md>.
• Inspect ownership with leaks --traceTree=<address>. "Found 0 roots" means an unreachable self-retained leak, so use leaks --groupByType.
• Do not claim a fix because the total count dropped. Show the specific type or ownership path disappeared after recapturing the same flow.
• Lazy allocation is a scope reduction, not a fix. Prefer deleting the retaining edge over cleanup code.
• If only framework noise appears, say so and recommend a narrower capture.
