fix: bumpy generate emits bump files for consumers of changed catalog entries

[theoephraim]

Fixes #152.

Problem

bumpy generate maps each commit to packages by directory containment. Catalog definitions live at the repo root (pnpm-workspace.yaml, .yarnrc.yml, package.json), so a commit that only bumps a catalog entry matches no package and is skipped — while bumpy check already flags every catalog: consumer as changed. Renovate/Dependabot catalog bumps therefore required hand-writing a bump file listing every consumer.

Fix

• New core/catalog-changes.ts holds the catalog diff that check had inline: getChangedCatalogEntries(rootDir, beforeRef, afterRef | null, changedFiles) plus findCatalogConsumers(packages, changes). loadCatalogsAt moved here from dep-bump-files.ts.
• generate now uses mapCommitToPackages(hash, …): directory containment as before, plus — when the commit touches a catalog file — the consumers of entries that changed between hash^ and hash. Applies to both the non-conventional path and the scopeless/unresolved-scope CC path. Explicit CC scopes still win.
• check uses the same helpers (behavior unchanged; touchesCatalogFiles short-circuits the git reads when no catalog file changed).
• Docs: cli.md "How commits are mapped" notes catalog handling.

Tests

Three integration tests in generate.test.ts (temp git repos): pnpm catalog bump maps to the consuming package only; bun/npm root package.json catalog + named catalog across dep fields; a root-level commit with no entry changes maps to nothing. Full suite 446 pass, tsc, lint and fmt clean.

Important

Historical catalog commits can still be skipped after a package-manager migration because catalog files at old refs are selected using the manager at the current HEAD.

Reviewed changes in 5e31485 cover the shared catalog-diff extraction and catalog-aware commit mapping added to bumpy generate.

• Shared catalog analysis: moves catalog loading, semantic diffing, and consumer matching into core/catalog-changes.ts for reuse by check, dependency bump planning, and generation.
• Commit-to-package mapping: extends scopeless/unresolved conventional commits and non-conventional commits to include consumers of catalog entries changed by each commit while preserving explicit scope precedence.
• Documentation and release metadata: documents catalog-aware mapping and adds the package bump file.
• Integration coverage: exercises pnpm catalogs, Bun/npm package.json catalogs, named catalogs, dependency fields, and non-semantic root-file changes.

✅ No new issues found.

Reviewed changes since the prior Pullfrog review cover historical package-manager detection and its regression coverage.

• Ref-aware package-manager detection: extracted detectPackageManagerFrom so catalog loading selects pnpm, Yarn, Bun, or npm from the files present at each requested Git ref.
• Migration regression coverage: added an integration test proving an earlier pnpm catalog bump remains attributable after the repository migrates to Yarn.
