Summary

Connects the process activity input from libnyanpasu/nyanpasu-utils#218 to managed core supervision, so the service's SCM Preshutdown pauses automatic core recovery and Windows stops kill the existing process tree without launching the Ctrl+C helper.

Stacks on #469. Depends on libnyanpasu/nyanpasu-utils#218. Refs libnyanpasu/clash-nyanpasu#6054.

Changes

• Pin nyanpasu-utils to a3ec581 (U1).
• Add optional process activity injection through CoreManagerBuilder, ProcessRuntimeBackend and InstanceBuilder into each supervisor: initial and replacement instances, recovery and shutdown. With no activity supplied, behavior is unchanged.
• The service host owns the activity source. On Preshutdown it publishes an irreversible Quiescing before cancelling the shared shutdown token from fix(service): bound Windows preshutdown and preserve cancellation #469. A plain Stop stays graceful.
• No changes to the IPC protocol or the CLI JSON output.

Verification

• Both new regression tests failed before the change and pass after it.
• WSL: 396 tests pass and 5 existing tests are ignored. clippy -D warnings, rustdoc and formatting pass. Cargo.lock is unchanged.
• The Windows-gnu checks stop in the aws-lc-sys build script (no mingw), so the Windows code paths here have only been reviewed by hand.

Windows acceptance

The process-tree and helper tests are not in the CI matrix, so run these manually on Windows:

• cargo test -p nyanpasu-utils --no-default-features --features process --test process_kill --test process_helper_smoke --test process_supervisor
• the core-manager lifecycle tests
• a real SCM Preshutdown/Stop check: Quiescing launches zero Ctrl+C helpers and kills the whole tree, and Stop stays graceful.

Follow-up

If #218 is squash-merged, re-pin nyanpasu-utils to the merged commit.
