Greptile Summary

This is an automated release PR generated by release-plz-pr, bumping the entire workspace from v1.8.0 to v1.9.0. All changes are mechanical: version strings, CHANGELOG entries, CLI docs, and Cargo.lock transitive dependency patch updates.

• All 12 workspace crates and the root Cargo.toml have their version field updated from 1.8.0 to 1.9.0, with matching CHANGELOG sections added to each crate.
• Cargo.lock reflects several minor dependency patch bumps (demand 2.0.1, h2 0.4.14, tokio 1.52.2, tower-http 0.6.9, redox_syscall 0.7.5, siphasher 1.0.3) and the removal of iri-string in favour of url as a tower-http transitive dependency.
• Supporting artifacts (release.json, aube.usage.kdl, docs/cli/commands.json, docs/cli/index.md) are updated consistently to reflect the new version.

Confidence Score: 5/5

Safe to merge — entirely automated version-bump and changelog generation with no logic changes.

Every changed line is either a version string, a CHANGELOG entry, a CLI doc update, or a transitive dependency patch bump in Cargo.lock. No application logic, configuration behaviour, or API contracts are modified.

No files require special attention.
