Release 1.0

[FusRoman]

Complete rewrite of Fink-FAT in Rust

The previous Python implementation relied heavily on Pandas and lacked the
performance and architectural clarity needed to scale to the volumes produced
by ZTF and Vera Rubin. This rewrite is a clean break from that codebase —
nothing has been carried over as-is.

What changed

• The entire codebase is now written in Rust.
• The linking pipeline is built around a graph-based architecture: photometric
  alerts are modeled as nodes, and candidate trajectories emerge from edge
  construction and resolution across nightly observation windows.
• No more Pandas. No more Python overhead at the algorithmic level.

Why a full rewrite

The Python version was not salvageable for the target scale. Rewriting in Rust
allows tight control over memory, parallelism (via Rayon), and latency — all
of which matter when processing millions of alerts per night.
