This PR prepares the v0.12.1 release by updating package versions and changelogs across all packages, examples, and apps in the monorepo.

## Changes Made

- **Version Bumps**: Updated all package.json files from v0.12.0 to v0.12.1 across:
  - 18 core packages (core, react, vue, svelte, etc.)
  - 16 example applications
  - Web documentation app

- **Changelog Updates**: Added v0.12.1 entries to all CHANGELOG.md files documenting:
  - Generation mode rename: `"generate"` → `"standalone"`, `"chat"` → `"inline"`
  - Fixed React duplicate module error in `@json-render/mcp`
  - Improved skill names (shortened from `json-render-*` format)
  - Updated dependency references

- **Documentation**: Updated the changelog page with detailed migration information for the generation mode changes

This is a coordinated release across the entire monorepo to maintain version consistency and provide users with the latest improvements and bug fixes.

+## v0.12.1
+
+March 2026
+
+### Changed: Generation Mode Names
+
+The generation mode values passed to `catalog.prompt()` have been renamed for clarity:
+
+- `"generate"` is now `"standalone"`
+- `"chat"` is now `"inline"`
+
+The old names are accepted as deprecated aliases and will emit a console warning. See the [Migration Guide](/docs/migration#generation-modes) for details.
+
+### Fixed: MCP React Duplicate Module Error
+
+Resolved a React duplicate module error in `@json-render/mcp` by adding Vite dedupe configuration. Also added a new `@json-render/mcp/build-app-html` server-safe entry point for building self-contained MCP App HTML without importing React.
+
+### Improved: Skill Names
+
+Skills have been renamed from `json-render-*` to shorter names (e.g. `json-render-react` → `react`, `json-render-core` → `core`).
