First release of postcrate-core to crates.io.

A Tokio-native SMTP capture engine for local development, integration tests, and CI. Powers the Postcrate desktop app and ships standalone — no Tauri, no UI, no third-party service.

Optional features:

postcrate-core = { version = "0.1", features = ["tls", "specta"] }
Feature Effect
tls Enables STARTTLS and implicit-TLS listeners (RFC 8314). Off by default.
