robobun edea077947 Fix env_loader allocator threading issue with BUN_INSPECT_CONNECT_TO (#22206) ...

## Summary
- Fixed allocator threading violation when `BUN_INSPECT_CONNECT_TO` is
set
- Created thread-local `env_loader` with proper allocator isolation in
debugger thread
- Added regression test to verify the fix works correctly

## Problem
When `BUN_INSPECT_CONNECT_TO` environment variable is set, Bun creates a
debugger thread that spawns its own `VirtualMachine` instance.
Previously, this VM would fall back to the global `DotEnv.instance`
which was created with the main thread's allocator, causing threading
violations when the debugger thread accessed environment files via
`--env-file` or other env loading operations.

## Solution
Modified `startJSDebuggerThread` in `src/bun.js/Debugger.zig` to:
1. Create a thread-local `DotEnv.Map` and `DotEnv.Loader` using the
debugger thread's allocator
2. Pass this thread-local `env_loader` to `VirtualMachine.init()` to
ensure proper allocator isolation
3. Prevent sharing of allocators across threads

## Test plan
- [x] Added regression test in
`test/regression/issue/test_env_loader_threading.test.ts`
- [x] Verified basic Bun functionality still works
- [x] Test passes with both normal execution and with
`BUN_INSPECT_CONNECT_TO` set
