fix(release): pin conventionalcommits preset to v9 and align release-note sections

[dawsontoth]

Why

Our semantic-release repos generate GitHub release notes with the conventionalcommits preset, but the behavior had drifted and, in several repos, notes were coming out empty. Two separate causes:

1. Preset v10 breaks rendering. @semantic-release/release-notes-generator@14 still bundles the Handlebars-based conventional-changelog-writer@8. The conventional-changelog-conventionalcommits v10 preset rewrote its templates as JS functions for the newer @conventional-changelog/template engine (writer@9); fed to writer@8 only the header survives, so every release note collapses to just its ## [x.y.z]… line.
2. presetConfig.types drift. Types like chore/chore(deps)/ci/build/style were hidden or missing, so dependency-only releases (the common Renovate case) produced empty notes.

This PR makes the repo consistent with studio's canonical release config (which surfaces every commit type) and holds the preset on v9 where relevant. Reference: HarperFast/studio#1560.

What changed

• conventional-changelog-conventionalcommits devDependency ^10.0.0 → ^9.3.1 (+ regenerated package-lock.json).
• Aligned .releaserc.json presetConfig.types to studio's superset.
• Added the Renovate guard.

Symptom fixed: v1.2.2 dropped a fix(renovate): commit and rendered header-only.

Canonical presetConfig.types (matches studio)

feat→Features, fix→Bug Fixes, perf→Performance Improvements, refactor→Refactoring, chore(deps)→Dependency Updates, chore→Chores, docs→Documentation, style→Styles, test→Tests, build→Build System, ci→Continuous Integration, revert→Reverts — nothing hidden, so no release comes out empty.

Renovate guard

Added a packageRules entry pinning conventional-changelog-conventionalcommits to <10 so Renovate won't re-introduce the v10 breakage. Remove once @semantic-release/release-notes-generator ships a writer@9-based major.

Verification

• .releaserc.json is valid JSON; renovate-config-validator passes.
• Lockfile regenerated (--package-lock-only); npm ci passes under npm 10.8.2 (the Node 20/22 CI matrix version). Lock diff is limited to the preset 10→9 swap — no unrelated churn.

Code Review

This pull request downgrades conventional-changelog-conventionalcommits to version 9.3.1 and pins it in renovate.json to avoid empty release notes caused by compatibility issues with @semantic-release/release-notes-generator. It also updates the release configuration in .releaserc.json. Feedback on the release configuration points out that the conventional-changelog-conventionalcommits preset does not support the scope property in the types array, meaning the duplicate chore entries will overwrite each other and prevent the "Dependency Updates" section from rendering. It is recommended to consolidate these entries.
