Set up the skyshift Cargo project

A terminal app (ratatui) to track work shifts, built on stable Rust,
edition 2024.

- Cargo.toml: eight well-known crates, each with a comment saying why:
  ratatui (UI), jiff (dates and time zones), serde + toml + serde_json
  (files), directories (per-OS folders), arboard (clipboard), anyhow.
- .cargo/config.toml: static C runtime on Windows, so the .exe runs
  without the Visual C++ Redistributable; `cargo lint` alias.
- rustfmt.toml: one formatting style for `cargo fmt`.
