Refactor downloadSocketBtmRelease API for caller-controlled paths

BREAKING CHANGE: downloadSocketBtmRelease now requires tool as first parameter
and accepts optional config as second parameter. Callers now have full control
over download directory structure.

Changes:
- Move tool from config object to required first parameter
- Make options parameter optional (was required config object)
- Add explicit | undefined to all optional parameters in config types
- Remove automatic /${toolName}/${platformArch} path nesting in downloadGitHubRelease
- Add tests validating new API signature

Migration:
Before: downloadSocketBtmRelease({ tool: 'lief', downloadDir: 'build' })
After:  downloadSocketBtmRelease('lief', { downloadDir: 'build' })
