fix(smol): skip CLI bootstrap for basic Node.js operations

The smol binary's bootstrap was trying to download the Socket CLI
on every invocation, including basic Node.js operations like:
- node -e '...' (eval mode)
- node --version
- node --help
- node (REPL)

This broke the smoke test during build because:
1. Smoke test runs: node -e 'console.log("✓ Binary can execute JavaScript")'
2. Bootstrap intercepts and tries to download @socketsecurity/cli@^X.X.X
3. Package doesn't exist on npm yet (unpublished version)
4. Download fails → build fails

Solution: Add shouldSkipCliBootstrap() check that detects:
- Eval mode (-e, --eval)
- Version/help flags (--version, -v, --help, -h)
- REPL mode (no arguments)
- Explicit skip (SOCKET_CLI_SKIP_BOOTSTRAP=1)

When detected, bootstrap returns 0 and lets Node.js execute normally.
This allows:
- Smoke tests to pass during build
- Using smol binary as a regular Node.js runtime
- Testing/debugging without CLI download

The CLI bootstrap still runs for actual CLI invocations.
