v0.2.0

Features

• Catalog: finish the heroicons migration (top bar, Alert, MessageScroller demos) — no more text-glyph icon placeholders
• Catalog: add an inline sidebar search bar for the component list
• Catalog: add a top-level Components/Create nav, with a redesigned Create page — theme picker (Style/Base Color/Accent) with per-option color swatches, live preview, and a copy-to-clipboard setup snippet
• Theme: add ShadcnRing.enabled toggle, now off by default (text inputs are unaffected — they always show their focus ring)
• ShadcnMessageScroller: add an icon override slot for the jump-to-bottom button
• ShadcnButton: add a pressed-state push effect

Fixes

• ShadcnText's muted/explicit color no longer gets silently overridden when nested inside a container that sets an ambient contentColor (ShadcnCard, ShadcnAlert, ShadcnTextField placeholders, ...)
• ShadcnCarousel: fix the Previous/Next buttons overlapping/clipping against the card edge
• Catalog: fix Create page dark-mode/theme-preset scoping — dark mode now applies everywhere (top bar included), while Style/Base Color/Accent pickers scope to the sidebar + content pane only
• Focus ring: fix a layout reflow bug by reverting to a dropShadow-based ring paired with shape
