This commit introduces a new `doctate-common` crate to the workspace. This crate will house shared data structures and constants used by both the `doctate-server` and any future clients. This refactoring helps to: - Reduce code duplication. - Improve maintainability by centralizing common logic. - Define a clear API contract for server-client communication. The following modules have been added: - `ack`: Contains `AckResponse` and `AckStatus` for server responses. - `constants`: Defines shared constants like API endpoints and multipart field names. - `timestamp`: Provides utilities for handling RFC3339 timestamps, including conversions to and from filesystem-safe strings.
