## Summary
- Fix NO_PROXY environment variable to properly respect port numbers
like Node.js and curl do
- Previously `NO_PROXY=localhost:1234` would bypass proxy for all
requests to localhost regardless of port
- Now entries with ports (e.g., `localhost:8080`) do exact host:port
matching, while entries without ports continue to use suffix matching
## Test plan
- Added tests in `test/js/bun/http/proxy.test.js` covering:
- [x] Bypass proxy when NO_PROXY matches host:port exactly
- [x] Use proxy when NO_PROXY has different port
- [x] Bypass proxy when NO_PROXY has host only (no port) - existing
behavior preserved
- [x] Handle NO_PROXY with multiple entries including port
- Verified existing proxy tests still pass

## Summary
- Disable HTTP keep-alive when a proxy returns a 407 (Proxy
Authentication Required) status code
- This prevents subsequent requests from trying to reuse a connection
that the proxy server has closed
- Refactored proxy tests to use `describe.concurrent` and async
`Bun.spawn` patterns
## Test plan
- [x] Added test `simultaneous proxy auth failures should not hang` that
verifies multiple concurrent requests with invalid proxy credentials
complete without hanging
- [x] Existing proxy tests pass

## Summary
- Fix out-of-bounds access when parsing `NO_PROXY` environment variable
with empty entries
- Empty entries (e.g., `"localhost, , example.com"`) would cause a panic
when checking if the host starts with a dot
- Skip empty entries after trimming whitespace
fixes BUN-110G
fixes BUN-128V
## Test plan
- [x] Verify `NO_PROXY="localhost, , example.com"` no longer crashes
