//! The adapter registry: the single place that knows which adapters beck
//! ships in this version.
//!
//! v0.2 ships exactly one adapter: `ClaudeCodeAdapter`. Cursor is
//! deferred to v0.3 (see `.rune/plan-beck-link-spec.md` ยง0). Phase 4
//! (`beck link`) and Phase 5 (`beck check`) call into this registry to
//! iterate the set.
//!
//! Keeping the set in code (not config) is deliberate: the binary size
//! budget rules out dynamic dispatch over user-supplied plugins, and the
//! CLI surface `--agent <name>` must be a closed set for tab-completion
//! and docs.
