base64-ng 1.0.1

[eldryoth]

base64-ng 1.0.1

Patch release focused on wider compiler compatibility, documentation clarity, and security hardening.

Highlights

• Lowered MSRV from Rust 1.95.0 to Rust 1.90.0
• Added README compatibility evidence for Rust 1.90.0 through 1.96.0
• Added README artwork and included image assets in the published package
• Added the 1.0.x source-layout roadmap before future 1.1 feature work

Security And Correctness

• Hardened wrapped line-ending detection with checked offset arithmetic
• Added DecodeError::StagingTooSmall so staged constant-time decode distinguishes undersized staging buffers from undersized output buffers
• Shared legacy-whitespace traversal between validation and decode paths to reduce drift risk
• Tightened BackendPolicy::HighAssuranceScalarOnly to require a CT result gate classified as a hardware speculation barrier
• Added a guarded transfer path when converting SecretBuffer into ExposedSecretString
• Strengthened docs for LineWrap::new, cleanup-boundary escape hatches, CT loop guard behavior, and runtime posture reporting

Validation

• Full local release gate passed on Rust 1.90.0
• Checks confirmed through Rust 1.96.0
• GitHub CI and CodeQL green
