[NO-ISSUE] feat(webkit): add Brand component consolidating the Azion logo lockups

[gab-az]

Summary

Adds Brand — a new content component (@aziontech/webkit/brand) that consolidates the loose @aziontech/webkit/svg/azion/* logo assets behind a single, documented API.

• kind ('default' | 'reduced' | 'extended', default default) selects the lockup:
  • default → the AZION wordmark
  • reduced → the "A" glyph for tight spaces
  • extended → the AZION wordmark with the "move to the edge technologies®" tagline
• size ('small' | 'medium' | 'large', default medium) sets the lockup height (16 / 24 / 32 px) while width scales automatically, so every kind keeps its own aspect ratio (swap kinds at the same size and they line up on height).
• Root is a role="img" element labeled Azion (consumer-overridable via aria-label); data-kind / data-size mirror the props; the inner SVG is aria-hidden.

Follows the full spec-driven pipeline: approved .specs/brand.md, component-scaffold patterns (inline utilities + data-* variants, no JS class presets), a co-located browser-mode test suite, a storybook-write-conformant story (Default + composite Types + Sizes), and a Code Connect mapping.

Notes

• Non-breaking / additive. New component + new ./brand export only. The existing svg/azion/* exports are kept and remain individually importable — nothing removed or renamed. semantic-release: minor.
• The brand SVG assets still embed the brand orange as a hex literal; documented as a theme gap in the spec (follow-up: tokenize to var(--primary)).
• Code Connect maps the Figma type variant (Default→default, Min→reduced, Full→extended); "Move to the Edge" is intentionally not exposed and size is a code-only prop.
• Verified: ESLint, vue-tsc, type-coverage (99.97%), vitest (21/21, real Chromium), and storybook build all pass.

Not included

The old AzionLogo Storybook story is left in place for now (it still documents the move-to-the-edge / full assets that Brand doesn't surface); removing/trimming it can be a follow-up.
