Add TOML dependency and new config/startup modules

The TOML dependency is added to `Cargo.lock` to support configuration
file parsing.
New modules `config` and `startup` are introduced in
`doctate-client-core`:
- `config`: Handles client configuration loading and saving, including
  defaults for polling intervals and window hours.
- `startup`: Contains routines for initial cleanup tasks, such as
  removing stale markers and orphan audio files based on defined
  retention periods.

//! Shared client configuration: server URL, API key, polling cadence,
//! oneliner window. Every native client (desktop, watch, phone) reads
//! the same schema — only the on-disk path differs per platform.
//!
//! Path resolution is deliberately **not** part of this module. Callers
//! provide a concrete `&Path` to `load_from` / `save_to`; the
//! per-platform path helper lives in each client crate.
