Replace @a2ui/lit with @a2ui/web_core 0.9, introduce createCatalog() API for
custom component catalogs, add basic (18 components) and minimal (5 components)
built-in catalogs, CSS variable theming for dark mode, eliminate XSS vector
(dangerouslySetInnerHTML removed from Text component).
`@a2ui/lit` registers the "a2ui-root" custom element via Lit's
@customElement decorator as a side effect when its UI module loads.
React Strict Mode double-mounts components, and since
customElements.define() is irreversible, the second mount throws:
"the name a2ui-root has already been used with this registry"
Several a2ui-renderer files used value imports from "@a2ui/lit" when
only types were needed, pulling in the full module tree including
the custom element registration. Changed to `import type` where
possible and switched to the narrower `@a2ui/lit/0.8` subpath
(core.js only, no UI/custom element registration) where value
access is needed.

Flatten all packages from packages/v1/* and packages/v2/* into packages/* —
every package now lives directly under the @copilotkit/ scope with no v1/v2
subdirectories.
- Move all v1 packages (react-core, react-ui, runtime, shared, etc.) from
packages/v1/* to packages/*
- Absorb v2 react code into packages/react-core/src/v2/ (exported via /v2 subpath)
- Absorb v2 agent code into packages/runtime/src/agent/ (exported via /v2 subpath)
- Move v2 packages (core, angular, demo-agents, etc.) to packages/*
- Replace all @copilotkitnext/* imports with @copilotkit/* equivalents
- Keep @copilotkitnext/angular as the sole exception (angular remains on next)
- Update CI workflows, renovate config, release scripts for flat structure
- No public API surface changes — all exports fields are preserved
