Release v0.3.0

Added

• New Chronicle.Projections.Projection macro for defining standalone declarative projections — keeps read model structs as pure data shapes while projection logic lives in a separate module.
• :projections option on Chronicle.Client to register declarative projection modules alongside :read_models; auto-discovered via otp_app: convention.
• Read model queries now wait for the Chronicle connection to be established before attempting requests, with configurable timeouts and clean error propagation when the connection is unavailable.

Fixed

• Model-bound from declarations with no options now correctly trigger auto-mapping instead of producing an empty property set.
• Console sample interactive input no longer requires pressing Enter after each keypress.
