📦 Switch Opaline from path dependency to published crate

Replace path = "../opaline" with version = "0.2.0" now that the theme
library has been published to crates.io. This completes the extraction
and publication workflow from commit 7f364d1 where git-iris became the
first consumer of the standalone library.

Maintains all feature flags: ratatui, gradients, global-state,
builtin-themes, discovery, and cli.
