chore: remove pinned rust toolchain

[jdx]

Summary

• remove rust-toolchain.toml
• let development, CI, and release environments use their configured default Rust toolchain
• use CI to expose any incompatibilities with the runner-provided compiler and Clippy

Validation

• git diff --check
• confirmed this environment selects its default stable toolchain, Rust 1.97.1, after removal

AI-assisted — Tool: Codex; model: openai/unavailable; version: unavailable.

Note

Low Risk
Configuration-only change with no application logic impact; the main effect is less reproducibility of local Rust versions across contributors.

Overview
Removes the repo-level rust-toolchain.toml that pinned Rust 1.95.0 and required clippy and rustfmt components.

Local builds and any environment that relied on that file will no longer auto-select that toolchain; they will use whatever Rust version is already configured (e.g. default stable on the machine or in CI). CI workflows that set toolchain explicitly are unchanged by this diff.

A rabbit found the toolchain file gone
No pinned Rust channel to carry on
Clippy and rustfmt hop free
The build now chooses its decree
Ears twitch in configuration dawn
