Yichen Jiang 93bba8ef67 fix(http-proxy): withhold NODE_USE_ENV_PROXY when the child receives a refused proxy value
`proxyEnvironmentForChild()` hands a child the proxy values the user
exported, including one this package refused — a SOCKS URL kept because
`curl` reads it — and sets `NODE_USE_ENV_PROXY=1` so a child Node honors
them. Node parses `HTTP_PROXY` and `HTTPS_PROXY` under that flag before
running the program and exits on any scheme other than `http:` or
`https:`. So a user with a usable `HTTP_PROXY` and `HTTPS_PROXY=socks4://…`
lost every Node child — stdio MCP servers, subagent CLIs, `npm` in the
bash tool — before its first line, while this process had reported only
that the scheme stayed direct. Measured on Node 24.17: `socks4://`,
`ftp://`, and a malformed value all exit 1; `socks5://` is accepted there
and only there.

The flag is now withheld whenever a value under the names Node parses is
one `isSupportedProxyUrl` refuses. Such a child connects directly, which
is what this process already said about that scheme, and `curl` still
reads the value it was kept for. Node does not read `ALL_PROXY`, so a
refused value there alone changes nothing.

The socks5 case in `install.spec.ts` now asserts the flag absent; the
ALL_PROXY fill case asserts it present; a new case spawns a real child
Node under the overlay for each refused shape and asserts it starts.
