Hashavatar 0.9.0

hashavatar 0.9.0

hashavatar 0.9.0 keeps the project as a single image-generation crate.

Highlights

• Bumped the crate to 0.9.0.
• Kept the public package as hashavatar only.
• Removed the near-term separate-core-crate direction from the roadmap.
• Kept deterministic identity hashing, public options, raster rendering, SVG
  rendering, and encoders together in the main crate.

Compatibility

• Raster/SVG output is intended to stay stable from 0.8.0.
• Existing render, SVG, encode, identity, and optional hash APIs are unchanged.
• There is no hashavatar-core crate to publish for this release.

Rationale

The project goal is avatar image generation. A separate public no_std + alloc
core crate would add release and API surface without serving that primary use
case. Lower-level planning boundaries can remain internal unless a future
image-generation feature needs them.
