feat(v11): add Carbon v11 support

[motou]

Closes #158

This PR adds full support for Carbon Design System v11 (cds-- prefix) alongside the existing v10 (bx--) support. Pages running v10, v11, or both simultaneously are all handled correctly.

Changelog

Component detection

• Added carbon-v11.js library using @carbon/react — 63 v11 React components detected via cds-- selectors
• Added carbon-web-components-v11.js using @carbon/web-components v2 — 85 cds- custom elements
• Added cloud-cognitive-v11.js using @carbon/ibm-products v2 — 104 IBM Products components
• Added ibmdotcom-v11.js using @carbon/ibmdotcom-web-components v2 — 74 IBM.com components
• Component-list now ships 10 libraries / 875 components total (up from 7 / ~500)
• All v11 libraries carry a version: 'v11' tag; inventory labels render as e.g. "Carbon for IBM Products (v11) :: Tearsheet"

Color Specs panel

• isCarbonV11Context() walks the DOM to detect cds-- ancestor classes
• v11 elements resolve against @carbon/themes v11 token names (background, layer-01, etc.)
• v10 elements continue resolving against v10 token names (ui-01, text-01, etc.)

Popup header

• Page validation detects bx-- and cds-- presence independently
• A blue version tag (v10, v11, or v10+v11) appears in the popup header

Dependencies

• v10 packages kept unchanged; v11 packages added as npm aliases (@carbon/themes-v11, @carbon/ibm-products-v2, @carbon/ibmdotcom-web-components-v2) to avoid conflicts
• Fixed a pre-existing bug in componentList.js where Object.assign was merging the whole library object instead of .components
