Main Mix task to generate the monolithic binary.

This task orchestrates the fetching of ERTS, packaging of the release/escript, and compilation of the Rust wrapper.

Batamanta supports two output formats:

• :release (default) - Full OTP release with supervisor tree
• :escript - Lightweight escript with embedded Elixir runtime

For projects using mix escript.build, use:

batamanta: [
  format: :escript
]

User specifies, user owns. If you specify otp_version, that exact version is used. If not specified (auto mode), a conservative fallback is used.

batamanta: [
]

In auto mode (no version specified), the system tries:

• 28.0 → 28.1 → 28.2 → ... (fallback to first available)

Batamanta handles its own garbage. After each successful compilation, it:

• Removes bat_cargo_cache from the system temp directory
• Deletes bat_pkg_* and bat_build_* intermediate folders
• Preserves the ERTS cache (~/.cache/batamanta) for sub-second repeat builds

To manually wipe the entire cache (including downloaded ERTS), use mix batamanta.clean.

Use :erts_target for unified platform specification:

batamanta: [
  execution_mode: :cli,
  compression: 3,
]

Force specific platform regardless of host:

batamanta: [
  force_arch: "x86_64",
  force_libc: "musl",
]

You can force the binary name by setting :binary_name in the config:

batamanta: [
  binary_name: "my_custom_binary"
]

mix batamanta

• --erts-target - Override ERTS target atom
• --otp-version - Specify exact OTP version (e.g., "28.1")
• --force-os - Force OS (linux, macos, windows)
• --force-arch - Force architecture (x86_64, aarch64)
• --force-libc - Force libc (gnu, musl) - Linux only
• --compression - Zstd compression level (1-19)
• --format - Output format: escript or release (default: release)
