fix(ci): Update MSRV to 1.82 for edition 2024 support

base64ct 1.8.0 requires edition 2024 which is not available in Rust 1.75.
Rust 1.82 (October 2024) has proper support for edition 2024 features.

Changes:
- Cargo.toml: rust-version = "1.82"
- .github/workflows/ci.yml: MSRV job uses Rust 1.82
- README.md: Badge shows 1.82+
- docs/03-DEV-SETUP.md: Updated prerequisites
- docs/13-GITHUB-RELEASE.md: Updated MSRV references
