The previous commit wrapped bun:test's `test` to bump the per-test
timeout default to 15s but cast the wrapper `as typeof _bunTest`
without copying the sub-properties (`.only`, `.skip`, `.each`,
`.todo`, `.failing`, `.if`) from the original. The cast was a lie:
the wrapper was a plain function, not the full callable with those
chained properties attached.
The file doesn't use any of them today, but a future test.only or
test.skip would fail with a cryptic "undefined is not a function."
Object.assign the original _bunTest's properties onto the wrapper so
sub-APIs chain correctly forever.
Surfaced by /ship's adversarial subagent.
