chore: release cargo-anvil 0.9.0

Bump cargo-anvil 0.8.0 -> 0.9.0 and regenerate CHANGELOG.md via
scripts/release-crate.ps1. On merge, automation tags the commit and
publishes the crate to crates.io.

This release carries #167 (catalog pins: cargo-coverage-gate 0.4.0,
cargo-heather 0.3.0) plus the accumulated fixes/perf since 0.8.0.

Also backfills the previously-missing [0.8.0] CHANGELOG section — 0.8.0
was tagged and published via #158 without a changelog entry — so the
history is contiguous.

Regenerated .anvil.lock (tool_version 0.8.0 -> 0.9.0).
