What/Why/How?

The bundle command now reports component renaming conflicts whenever two external definitions share the same name but have different content.

Reference

close #2691

Note

Medium Risk
Changes component naming during bundling and when/what warnings/errors are emitted, which can alter generated $ref targets and potentially break snapshots or downstream expectations.

Overview
Fixes bundle/bundle-oas so component renaming conflicts are detected even when same-named components come from different files (including pointer refs), honoring --component-renaming-conflicts-severity.

Updates component name generation to use the JSON pointer basename (with proper unescaping) and consistently suffix (-2, -3, …) on true content conflicts, which can change bundled $ref paths. Adds new fixtures/tests and updates snapshots to cover pointer-ref conflicts and dotted component keys.

It's the same as renameSource = renameSource || name or

if (!renameSource) {
  renameSource = name;
}

The issue here is that the bundler doesn't apply renaming consistently. If the schema wasn't referenced with a JSON pointer inside the file, it would behave correctly.

Hardcoded "schemas" in message for all component types

Medium Severity

The conflict message always says "Two schemas are referenced with the same name but different content" regardless of the actual component type. The componentType parameter (e.g., "parameters", "examples") is available in getComponentName but not used. With the simplified naming logic in this PR, the message now fires for examples and parameters conflicts where it previously didn't (e.g., the firstfirst-2 rename is an examples conflict, the UserUser-2 rename is a parameters conflict), making the misleading wording visible to more users.
