v0.2.0

v0.2.0

Release scope:

• Repository release for the HigherGraphen Rust workspace at 0.2.0.
• CLI binaries: casegraphen and highergraphen.
• Provider-neutral CLI skill bundle at 0.5.0.
• JSON schemas, fixtures, examples, docs, repository-owned skills, public .casegraphen traces, license, and commercial boundary.

Highlights:

• Added deterministic PR review target workflows for deriving review inputs from Git changes and recommending structural review targets.
• Added abstract coverage, weighted coverage, topology, and persistent homology concepts to generic higher-graphen-* packages for reuse beyond PR review.
• Added structural boundary signals that catch parent module wiring and command dispatch changes during PR review target selection.
• Expanded CaseGraphen topology surfaces, including focused topology and topology diff reports for workflow and native case history.
• Updated docs, skills, schemas, fixtures, and the provider-neutral CLI skill bundle to reflect the current CLI integration surface.

Publication decisions:

• Cargo packages are not published to crates.io in this release because workspace packages currently set publish = false.
• Provider marketplace publication, MCP server publication, and provider-specific manifests remain out of scope.
• This release publishes a Git tag, GitHub Release, and Darwin arm64 binary artifacts after explicit maintainer approval.
