[FEAT] emit tools as `metadata.tools.components`

[hakandilek]

Describe the feature

Own tools (@cyclonedx/cyclonedx-npm and @cyclonedx/cyclonedx-library) are listed under medatada.tools which is deprecated. They should be listed under medatada.tools.components as suggested since CycloneDX v1.5.

To Reproduce

Any generated JSON document contains the same output. I've tried the following command on an npm project:

npx @cyclonedx/cyclonedx-npm --flatten-components --short-PURLs --spec-version 1.6 --output-format JSON --output-file - --omit dev --omit optional

Expected behavior

Entries under metadata.tools should be listed under medatada.tools.components according to the "component" data structure.

Environment

• @cyclonedx/cyclonedx-npm version: 1.19.3
• NPM version: 10.9.0
• Node version: v23.1.0
• OS: MacOS 14.7 (23H124)

Additional context

This is the part of the code where metadata.tools are being populated:

cyclonedx-node-npm/src/builders.ts

Lines 230 to 238 in 96f1046

	bom.metadata.tools.add(new Models.Tool({
	name: 'npm',
	version: npmVersion // use the self-proclaimed `version`
	// omit `vendor` and `externalReferences`, because we cannot be sure about the used tool's actual origin
	// omit `hashes`, because unfortunately there is no agreed process of generating them
	}))
	for (const tool of this.makeTools()) {
	bom.metadata.tools.add(tool)
	}

I've missed that one. You're right. It's probably better to wait on this one and adopt here accordingly.

this is a breaking change.
not a blocker, just a remark.
