Fixes EXSC-1328

Why did I implement it this way?

script/utils/node-runtime-fence.test.ts fails on main with spawnEnv is not defined, which turns run-ts-tests red on every open PR. #2597 added the "runs where no IPC socket can be bound" test calling a spawnEnv() helper copied from propose-funnel-fence.test.ts, and #2618 removed that helper from this file without updating the new test.

The fence children run node --import tsx, which does not read .env, and the fence scripts do not load dotenv. So the child env is built from scratch with freshChildEnv() (per [CONV:TEST-SPAWN-ISOLATION]) instead of copying the test process's env:

• node-runtime-fence.test.ts: both spawning tests use freshChildEnv. The refusal test pins NODE_ENV=test, which it previously inherited from bun test: under any other value consola's fancy reporter strips the backticks the asserted message carries.
• propose-funnel-fence.test.ts: the local spawnEnv helper is removed. The two direct node --import tsx spawns use freshChildEnv; the bun lint:funnel spawn keeps withheldEnv(), because bun reloads .env for every name the passed env leaves unset.

Walkthrough

The no-IPC-socket test now uses freshChildEnv() to build its subprocess environment. The test retains its explicit TMPDIR and NODE_ENV settings.

- Line 210: Update the child environment setup around `withheldEnv()` to use
`freshChildEnv()` so inherited `NODE_OPTIONS` cannot trigger debugger output;
preserve credential withholding and the existing explicit environment overrides.
