## Summary
- When running `bun <file>` on a file with an unsupported type (e.g.,
`.css`, `.yaml`, `.toml`), Bun now shows a helpful error message instead
of the misleading "File not found"
- Tracks when a file is resolved but has a loader that can't be run
directly
- Shows the actual file path and file type in the error message
**Before:**
```
error: File not found "test.css"
```
**After:**
```
error: Cannot run "/path/to/test.css"
note: Bun cannot run css files directly
```
## Test plan
- [x] Added regression test in `test/regression/issue/1365.test.ts`
- [x] Test verifies unsupported files show "Cannot run" error
- [x] Test verifies nonexistent files still show "File not found"
- [x] Test fails with `USE_SYSTEM_BUN=1` and passes with debug build

## Summary
- Wrap all tests in `describe.concurrent` at module scope for parallel
test execution
- Replace `Bun.spawnSync` with `Bun.spawn` + `await` throughout
- Replace `run_dir`/`writeFile` pattern with `tempDir` for automatic
cleanup via `using` declarations
- Remove `beforeEach` hook that created shared temp directory
## Test plan
- [x] All 291 tests pass with `bun bd test
test/cli/install/bun-run.test.ts`
- [x] All tests pass with `USE_SYSTEM_BUN=1 bun test
test/cli/install/bun-run.test.ts`

* Use Output.panic instead of garbled text
* Formatting
* Introduce `bun.sys.File`, use it for `Output.Source.StreamType`, fix nested Output.scoped() calls, use Win32 `ReadFile` API for reading when it's not a libuv file descriptor.
This lets us avoid the subtle usages of `unreachable` in std.os when writing to stdout/stderr.
Previously, we were initializing the libuv loop immediately at launch due to checking for the existence of a bun build --compile'd executable. When the file descriptor is not from libuv, it's just overhead to use libuv
cc @paperdave, please tell me if Iany of that is incorrect or if you think this is a bad idea.
* Fix closing undefined memory file descriptors in spawn
cc @zackradisic
* pause instead of close
* Fix poorly-written test
* We don't need big numbers for this test
* sad workaround
* fixup
* Clearer error handling for this test
* Fix incorrect test
@electroid when ReadableStream isn't closed, hanging is the correct behavior when consuming buffered data. We cannot know if the buffered data is finished if the stream never closes.
* Fix build
* Remove known failing on windows
* Deflake
* Mark no longer failing
* show all the failing tests
* Sort the list of tests
* fix argument handling
* dont show "posix_spawn" as an error code on windows

cc @paperdave. Signals can be run from any thread. This causes an assertion failure when the receiving thread happens to not be the main thread. Easiest to reproduce on linux when you spawn 100 short-lived processes at once.
