chore(release): bump packages to 0.16.0 - #393

Summary

• bump all 12 public packages and internal Askable dependency ranges to 0.16.0
• publish v0.16 release notes covering resumable Qwik actions, MCP CLI/resources, protocol documentation, and reliability fixes
• repair the MCP Registry manifest against its official schema, include it in the npm package, and add a CI consistency guard
• keep standalone examples on the latest actually published release during the release window, while repairing their stale 0.11/0.14 lockfiles to 0.15
• update current and versioned documentation references to v0.16.0

Version choice

This is a minor release because the grouped delta since v0.15.0 includes user-facing MCP capabilities, framework exports, Qwik API behavior, and new protocol/source documentation in addition to fixes.

Validation

• full monorepo build and all workspace tests
• browser E2E suite across Chromium, Firefox, and WebKit (134 passed, 1 skipped)
• versioned VitePress documentation build
• dry-run packaging for all 12 public workspaces
• production analytics example build and React Native example typecheck
• official MCP Registry JSON Schema validation plus repository release guards
• Qwik release-note snippet typecheck

Post-release example sync

Examples intentionally remain on the currently published 0.15 line until 0.16.0 exists on npm, avoiding ETARGET during this PR. The registry-aware CI guard will require them to advance to ^0.16.0 immediately after publication, when their lockfiles can be regenerated with real integrity metadata.
