Hashavatar 1.0.1

hashavatar 1.0.1

1.0.1 is a maintenance and documentation release for hashavatar.

Changed

• Refreshed compatible transitive dependencies in Cargo.lock and
  fuzz/Cargo.lock.
• Updated the GitHub CI taiki-e/install-action pin to v2.79.14.
• Lowered the manifest and toolchain MSRV to Rust 1.90.0 after validating the
  release gate and compatibility matrix.
• Added a polished README header with the project image, documentation links,
  and Rust version support table.
• Kept the README image in the repository while excluding .github/images/**
  from the published crate package.

Security And Hardening

• Added a debug assertion for out-of-range internal identity digest byte access
  so future renderer mistakes fail in debug/test builds while release builds
  remain non-panicking.
• Changed AvatarSpec::pixel_count() and AvatarSpec::rgba_buffer_len() to
  use saturating multiplication as defense-in-depth for future dimension-limit
  changes.
• Clarified that the transient by-value seed argument passed to
  StdRng::from_seed is part of the documented zeroization residual.

Compatibility Evidence

• Rust 1.90.0: full release gate.
• Rust 1.91.0 through 1.96.0: cargo check --features all-formats.
• Rust 1.90.0: additional checks for blake3 all-formats and
  xxh3 all-formats.
