## Summary
Fixed `http.request()` and `https.request()` hanging indefinitely when a
GET request includes a body (via `req.write()`).
### Approach
Instead of adding a public `allowGetBody` option to `fetch()`, this PR
creates a dedicated internal function `nodeHttpClient` that:
- Uses a comptime parameter to avoid code duplication
- Allows body on GET/HEAD/OPTIONS requests (Node.js behavior)
- Is only accessible internally via `$newZigFunction`
- Keeps the public `Bun.fetch()` API unchanged (Web Standards compliant)
### Implementation
1. **fetch.zig**: Refactored to use `fetchImpl(comptime allow_get_body:
bool, ...)` shared implementation
- `Bun__fetch_()` calls `fetchImpl(false, ...)` - validates body on
GET/HEAD/OPTIONS
- `nodeHttpClient()` calls `fetchImpl(true, ...)` - allows body on
GET/HEAD/OPTIONS
2. **_http_client.ts**: Uses `$newZigFunction("fetch.zig",
"nodeHttpClient", 2)` for HTTP requests
## Test plan
- [x] Added regression test at `test/regression/issue/26143.test.ts`
- [x] Test verifies GET requests with body complete successfully
- [x] Test verifies HEAD requests with body complete successfully
- [x] Test verifies `Bun.fetch()` still throws on GET with body (Web
Standards)
- [x] Test fails on current release (v1.3.6) and passes with this fix
