Replace `catch bun.outOfMemory()`, which can accidentally catch
non-OOM-related errors, with either `bun.handleOom` or a manual `catch
|err| switch (err)`.

## Summary
- Fixes a crash where invalid slice bounds caused a panic with message:
"start index N is larger than end index M"
- The issue occurred in `js_lexer.zig:767` when calculating string
literal content slice bounds
- Adds proper bounds checking to prevent slice bounds violations
- Includes regression test to prevent future occurrences
## Root Cause
The crash happened when `suffix_len` was larger than `lexer.end`,
causing the calculation `lexer.end - suffix_len` to result in a value
smaller than the `base` position. This created invalid slice bounds like
`[114..113]`.
## Solution
Added bounds checking to ensure:
1. `end_pos` is calculated safely: `if (lexer.end >= suffix_len)
lexer.end - suffix_len else lexer.end`
2. `slice_end` is always >= `base`: `@max(base, end_pos)`
## Test Plan
- [x] Added regression test in
`test/regression/issue/jsx-template-string-crash.test.ts`
- [x] Test verifies no crashes occur with JSX template string patterns
- [x] Verified normal template string functionality still works
- [x] All tests pass

* 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.

@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.

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.
