v0.16.0

Renames interfaces to contracts, tightens `depends_on` slot validation, and fixes macOS container builds.

Released on July 13, 2026

The conforms_to manifest field has been renamed to implements as part of a broader rename of "interfaces" to "contracts"; rename conforms_to to implements in your peppy.json5 and update any "interface" wording to "contract".
Dependency slots (depends_on) now require a single producer each, replacing the previous from_any binding model, and peppy now fails validation whenever a depends_on slot is left unfulfilled; update your bindings so every slot names exactly one producer.

macOS container builds no longer silently default to $HOME and now use the current working directory.
The peppy data root is now mounted into the Lima VM so container builds and runs can access it.
Fixed a hang where restarting the Lima VM blocked the async runtime while registering a host mount for the first time.
Container Python bindings no longer ship stale native extensions after shared-crate changes.

Contract (implements) validation failures now report per-slot coverage mismatches instead of a single combined string.
The CLI info output formatting has been simplified.

The advanced guides now include Python examples alongside the existing Rust examples.
The Python async examples now wrap select! in a loop and hold references to asyncio tasks so they are not cleaned up or garbage-collected prematurely.
