Josh McKinney de59e550c0 test: deflake nextest child-process leak in MCP harnesses (#11263) ...

## Summary
- add deterministic child-process cleanup to both test `McpProcess`
helpers
- keep Tokio `kill_on_drop(true)` but also reap via bounded `try_wait()`
polling in `Drop`
- document the failure mode and why this avoids nondeterministic `LEAK`
flakes

## Why
`cargo nextest` leak detection can intermittently report `LEAK` when a
spawned server outlives test teardown, making CI flaky.

## Testing
- `just fmt`
- `cargo test -p codex-app-server`
- `cargo test -p codex-mcp-server`


## Failing CI Reference
