Charlie Marsh ea7e0714da Fix relative MCP server spawning on macOS (#42117)
## Why

Rust falls back to `fork` when a macOS command combines a relative executable
path with a working directory, due to a historical `posix_spawnp` issue. This
can make local MCP server startup less reliable.

## What changed

- Spawn relative macOS MCP executables directly with `posix_spawn`, preserving
  the configured path, `argv[0]`, working directory, environment, stdio, and
  process group.
- Keep the existing launcher for `PATH` lookup and executable text files without
  a shebang.
- Use one local child wrapper for legacy and 2026-07-28 protocol framing, with
  cancellation-safe waiting and cleanup that kills and reaps dropped children.

## Testing

Add macOS regression coverage for relative scripts, argument and descriptor
preservation, launch errors, cancelled waits, and cleanup after runtime shutdown.
