molt v0.2.0

Transport Glue — call Go/Rust functions from Python over IPC

The biggest new feature: declare [[tool.molt.glue]] blocks in your project config and
molt sync auto-generates a typed Python module that calls your Go or Rust code through
a zero-configuration IPC server. No .so, no cgo, no ABI constraints — any type that
survives JSON round-trip works.

• Go support — local packages (src = "./mylib"), Go stdlib (src = "crypto/sha256"),
  and third-party modules (src = "golang.org/x/crypto/sha3"). Third-party: go get runs
  automatically. Stdlib: clean go.mod, no require entries needed.
• Rust support — thin adapter .rs file (src = "compress_glue.rs") included directly
  into the generated server via include!. Extra crates added to the generated Cargo.toml
  via crates = [...].
• Three transports: stdio (subprocess per Python process, default), unix_socket
  (persistent daemon, concurrent threads), tcp (network-addressable daemon).
• Type system: i32/i64/f32/f64/bool/string/bytes/[]i32/[]f64/[]string/json — full
  bidirectional mapping between Go, Rust, Python, and JSON wire format. bytes args/returns
  are base64-encoded on the wire, transparent in Python.
• Python shim fix: re-writes python/python3 shims after glue build so the glue
  directory is included in the hardcoded PYTHONPATH inside the shim.
• Typed stubs: .pyi files generated alongside .py clients for full IDE completion.
• Glue driver system: ~/.molt/glue-drivers.yaml for custom language drivers; built-in
  drivers for Go and Rust; extensible to Nim, Zig, Crystal, etc.
• CLI: molt glue list/show/regen/start/stop and molt glue-driver list/show/add.
• 3 new demos: 19 (Go stdio), 20 (Go library imports), 21 (Rust unix_socket).
• Site: 21 demos, Transport Glue feature card, demos 19–21 on GitHub Pages.
