v0.7.0 — DropdownMenu side: left/right + create-page shadcn parity

Kit

• DropdownMenuContent side: :left / :right (#34) — the panel can now open beside its trigger, joining :bottom/:top. Anchor-positioned (position-area: inline-end/-start span-block-end) with a flip-inline viewport fallback, mirroring shadcn's side prop. Invalid sides fail loud.

Dummy app (docs site)

• /create rebuilt to match ui.shadcn.com/create (#34, #35): a fixed app shell where only the canvas scrolls (both axes); two demo screens (01 finance, 02 smart home + artist) switched by the floating pill; and a like-for-like Customizer sidebar — seven side-right picker rows with working Theme / Icon Library / Heading / Font / Chart Color knobs, shareable --preset <code> bundles, Open Preset dialog, Shuffle, and Get Code.

Suite green (263 runs, +5 assertions). Verified interactively in Chrome and WebKit 26.5.
