fix(docs): update README

[Dazzanova]

Summary

• Update all 6 README files to say Rust 1.96.1 instead of Rust 1.93.0.
• Keep the documented Rust version consistent with rust-toolchain.toml and CONTRIBUTING.md.

Problem

• The README and all translated README versions currently instruct contributors to install Rust 1.93.0.
• The repository actually pins Rust 1.96.1 in rust-toolchain.toml, and CONTRIBUTING.md already documents 1.96.1.

Solution

• Updated the Rust version from 1.93.0 to 1.96.1 in all six affected README files:
  • README.md
  • docs/README.zh-CN.md
  • docs/README.de.md
  • docs/README.ja-JP.md
  • docs/README.ko.md
  • docs/README.ur-pk.md
• The documented version now matches the repository's rust-toolchain.toml and CONTRIBUTING.md.

Poem

A rabbit checks the version line,

“One point nine six!” the tools align.
Rustfmt hops, Clippy gleams,
Six README paths now match their schemes.
The build guide springs fresh and bright.
