/**
 * [WHO]: Public extensions subpath exports for SDK embedders that need to register optional built-in extensions
 * [FROM]: Depends on extensions/optional/evolution/* factory modules and their stable type surface
 * [TO]: Consumed by advanced SDK users importing @catui/agent/extensions
 * [HERE]: extensions.ts - package subpath entry that exposes optional extension factories without leaking implementation paths
 *
 * Design note: This subpath is intentionally narrow. CLI and SDK share the same
 * `additionalExtensionPaths` mechanism on `createAgentSession`. CLI users get
 * extension paths through settings/defaults; SDK users get them through this
 * subpath. Both paths converge on the same extension loader; no parallel CLI
 * surface exists.
