chore: release cargo-anvil 0.9.0

[Pato Sandaña (psandana)]

What

Release cargo-anvil 0.9.0 — version bump + regenerated changelog via scripts/release-crate.ps1. On merge, automation tags the commit and publishes the crate to crates.io.

Why now

This is the release that carries #167 (catalog pins cargo-coverage-gate 0.4.0 / cargo-heather 0.3.0) onto crates.io, so downstream consumers (e.g. the internal substrate flavor) can pick the new pins up by bumping their cargo-anvil dependency. It also ships the accumulated fixes/perf since 0.8.0.

Contents (v0.8.0..HEAD)

• 🐛 retry oversized Windows coverage exports (fix(cargo-anvil): retry oversized Windows coverage exports #166)
• 🐛 make anvil-fmt actually run the pinned nightly rustfmt (fix(cargo-anvil): make anvil-fmt actually run the pinned nightly rustfmt #159)
• 🐛 address validation follow-ups (fix(cargo-anvil): address validation follow-ups #131)
• 🐛 remove Bash from ADO steps (fix(cargo-anvil): remove Bash from ADO steps #160)
• ⚡ parallelize Miri test artifacts (perf(cargo-anvil): parallelize Miri test artifacts #123)
• 🏗️ bump cargo-coverage-gate and cargo-heather catalog pins (build(anvil): bump cargo-coverage-gate and cargo-heather catalog pins #167)

Also in this PR

• Backfilled the missing [0.8.0] CHANGELOG section. 0.8.0 was tagged (cargo-anvil-v0.8.0) and published via feat(anvil): replace legacy CI with aggregate gate #158 without a changelog entry, leaving a gap between [0.9.0] and [0.7.0]. Restored it (breaking feat(cargo-anvil)!: identify the ADO stage on every job wrapper invocation #154, feat feat(anvil): replace legacy CI with aggregate gate #158, fix fix(cargo-anvil): let the container image resolve the declared MSRV #155) so the history is contiguous. Also dropped a stray duplicate [0.8.0] - Initial release. block that release-crate.ps1 appended at the end of the file, so there is now a single, correctly-ordered [0.8.0] section.
• Regenerated crates/cargo-anvil/README.md with cargo-doc2readme (pinned 0.7.3) so the version-embedded docs.rs intra-doc links and the encoded [__cargo_doc2readme_dependencies_info] blob track the 0.9.0 bump — the anvil-readme-check compares that blob's recorded dependency versions against the crate's current requirements, so a stale 0.8.0 blob fails the check.
• Regenerated .anvil.lock (tool_version 0.8.0 → 0.9.0) so regenerate-check stays green.

Validation

• cargo test -p cargo-anvil — all green (415+ tests).
• cargo anvil --dry-run — clean (no generated-content or .anvil.lock drift).
• cargo doc2readme --lib --check (in crates/cargo-anvil) — Readme is up to date.

Notes: the [Unreleased] header is emitted by release-crate.ps1.

Fixed in 261e00a. Removed the stray duplicate [0.8.0] - Initial release. block that release-crate.ps1 appended at the end of the file. There is now a single, correctly-ordered [0.8.0] section (the detailed one with #154/#158/#155).

🟡 Changes recommended

The changelog currently contains a duplicate 0.8.0 section (conflicting with the earlier 0.8.0 entry), which should be corrected before publishing release notes.

crates/cargo-anvil/CHANGELOG.md:170

• The changelog contains two separate ## [0.8.0] - 2026-09-04 sections (one near the top and another appended at the end). This makes the release history ambiguous and the trailing - Initial release. line conflicts with the detailed 0.8.0 entries above. Remove the duplicate trailing 0.8.0 section so 0.8.0 is defined exactly once.

## [0.8.0] - 2026-09-04

- Initial release.

Addressed in 261e00a. The README is now regenerated with cargo-doc2readme (pinned 0.7.3) rather than hand-edited — both the docs.rs links and the encoded [__cargo_doc2readme_dependencies_info] blob now reflect 0.9.0, and cargo doc2readme --lib --check reports Readme is up to date. The PR description has been updated to match (it no longer claims No crate README changes).

🔵 Needs a closer look

crates/cargo-anvil/CHANGELOG.md currently contains a duplicate/conflicting 0.8.0 section at the end, which makes the release notes inconsistent.

crates/cargo-anvil/CHANGELOG.md:170

• The changelog now contains a second "## [0.8.0] - 2026-09-04" section at the end ("- Initial release."), which duplicates and contradicts the earlier 0.8.0 entry (lines 22-35). This will confuse consumers and makes the release notes inconsistent.

## [0.8.0] - 2026-09-04

- Initial release.

crates/cargo-anvil/README.md:422

• PR description says there are no crate README changes, but this diff updates docs.rs links and the doc2readme dependency-info footer to 0.9.0. Please either update the PR description to reflect the README regen or revert the README changes so the description and patch agree.

Closing as a duplicate. 👍

martin-kolinek pointed out (in the Please Review thread) that this release was already handled by #164 (chore(cargo-anvil): release v0.9.0 by st-dev-gh), which merged at 17:25Z — before this PR's auto-merge was even armed. main already carries cargo-anvil 0.9.0 with the same [0.9.0]/backfilled [0.8.0] CHANGELOG, and #164 is a superset (it also fixed scripts/release-crate.ps1 and regenerated the READMEs — the two things I had to patch manually here).

So the goal of #170 — publishing 0.9.0 (carrying #167's cargo-coverage-gate 0.4.0 / cargo-heather 0.3.0 pins) to crates.io — is already accomplished by #164. Nothing further needed here.
