## Summary
- Fixed `BUN_OPTIONS` environment variable not being applied as runtime
options for standalone executables (`bun build --compile`). Previously,
args from `BUN_OPTIONS` were incorrectly passed through to
`process.argv` instead of being parsed as Bun runtime options
(`process.execArgv`).
- Removed `BUN_CPU_PROFILE`, `BUN_CPU_PROFILE_DIR`, and
`BUN_CPU_PROFILE_NAME` env vars since `BUN_OPTIONS="--cpu-prof
--cpu-prof-dir=... --cpu-prof-name=..."` now works correctly with
standalone executables.
- Made `cpu_prof.name` and `cpu_prof.dir` non-optional with empty string
defaults.
fixes#21496
## Test plan
- [x] Added tests for `BUN_OPTIONS` with standalone executables (no
`compile-exec-argv`)
- [x] Added tests for `BUN_OPTIONS` combined with `--compile-exec-argv`
- [x] Added tests for `BUN_OPTIONS` with user passthrough args
- [x] Verified existing `compile-argv` tests still pass
- [x] Verified existing `bun-options` tests still pass
