fix(net): match socket overload native ABI

[proggeramlug]

What failed

Release candidate d118653 reproducibly timed out test_gap_net_connect_bound_value. Focused five-run diagnostics isolated the regression to #8814; trace run 32874761890 showed no-argument socket.end entering js_ext_net_socket_end3 with a bogus 244-byte final payload on every attempt. The echoed garbage re-entered the data handler, issued a second end on the half-closed socket, and failed with EPIPE.

Fix

• Use the floating-point ABI for the three NaN-boxed write/end arguments, matching the Rust FFI signatures. Missing arguments are now padded with the actual NaN-boxed undefined value.
• Add a table-level regression assertion for both overloads.
• Put hard process-level limits around Windows LLVM download and extraction. In release run 32863651704 two Windows jobs completed setup in 52-80 seconds, while the doc-test runner wedged in the same composite step for nearly the full two-hour job budget.

Validation

• cargo fmt --all -- --check
• git diff --check
• composite action YAML parse
• ./scripts/pre-tag-check.sh --quick
• trace evidence: run 32874761890, five identical failures before the fix

The release will still run the focused fixture five times on this exact SHA before merge, then Full CI and Simulator on a fresh post-merge candidate.

Summary by CodeRabbit

• Bug Fixes
  • Fixed net.Socket.write() and net.Socket.end() handling to correctly pass arguments through the native interface.
  • Improved Windows LLVM downloads and extraction with timeouts and fallback handling, reducing the risk of prolonged hangs.

📝 Walkthrough

Walkthrough

The change corrects native ABI descriptors for net.Socket.write() and end(). It also bounds Windows LLVM download and extraction with quoting, timeouts, fallback extraction, output validation, and exit-status checks.

Changes

Native socket ABI

Layer / File(s)	Summary
Socket signature ABI correction and regression coverage crates/perry-codegen/src/lower_call/native_table/net_events.rs, crates/perry-codegen/src/lower_call/native_module_dispatch.rs, changelog.d/8831-release-net-abi.md	net.Socket.write and end now use three F64 argument descriptors. A regression test verifies both dispatch signatures. The changelog records the ABI correction and Windows process limits.

Windows LLVM process bounds

Layer / File(s)	Summary
Bounded LLVM download and extraction .github/actions/setup-llvm22/action.yml	The action quotes the archive path, applies a two-minute tar.exe timeout, and supports a forced 7-Zip fallback. The fallback uses a five-minute timeout and validates executable availability, exit status, and the extracted output directory.

lists, including the curl.exe invocation and the corresponding tar.exe
