0315c97e7b Fix argv handling for standalone binaries - remove extra executable name (#22157) (#22169)
## Summary

Fixes an issue where compiled standalone binaries included an extra
executable name argument in `process.argv`, breaking code that uses
`node:util.parseArgs()` with `process.argv.slice(2)`.

## Problem

When running a compiled binary, `process.argv` incorrectly included the
executable name as a third argument:

```bash
./my-app
# process.argv = ["bun", "/$bunfs/root/my-app", "./my-app"]  # BUG
```

This caused `parseArgs()` to fail with "Unexpected argument" errors,
breaking previously valid code.

## Solution

Fixed the `offset_for_passthrough` calculation in `cli.zig` to always
skip the executable name for standalone binaries, ensuring
`process.argv` only contains the runtime name and script path:

```bash  
./my-app
# process.argv = ["bun", "/$bunfs/root/my-app"]  # FIXED
```

## Test plan

- [x] Added regression test in `test/regression/issue/22157.test.ts`
- [x] Verified existing exec-argv functionality still works correctly  
- [x] Manual testing confirms the fix resolves the parseArgs issue

Fixes #22157
