test(cli): loosen flaky header-timeout no-abort case

[marius-kilocode]

The provider/header-timeout.test.ts suite intermittently fails one case on CI, and a recent attempt to stabilize it (c319334) didn't fully fix the flake.

Problem

The headerTimeout does not abort delayed SSE body after headers arrive test (the only case that expects the timeout to not fire) used a 50ms header window with a 250ms delayed body. On a loaded CI runner the in-process server's headers and SSE prelude don't reach the client within 50ms, so the header-timeout timer fires and aborts the stream. result.text then rejects instead of resolving to "late", and the file fails on both attempts.

The other two timing cases (chunkTimeout and headerTimeout aborts when headers don't arrive) want the timeout to fire, so CI slowness makes them more reliable, not less. Only this one race-fails.

Change

• headerTimeout: 50 -> 500 (10x margin for CI jank)
• body delay 250 -> 1000

The body still lands well past the header window, so the assertion keeps its meaning: a healthy stream whose body arrives after headers should not be aborted by the header timeout (the timer is cleared on header arrival). Both edited lines are in a shared upstream test file, so they carry kilocode_change markers.

Could not run the suite locally (worktree has no node_modules and this sandbox has no network to bun install); the change is two numeric literals with no typecheck/lint impact.
