docs(Output): Restructure CHANGELOG with v2.0 release entries

Comprehensive update to the Output component's changelog introducing a new versioning format and detailed release notes. Key changes:
- Migrate from semantic versioning [0.x.x] to [vX.X] format aligned with Keep a Changelog
- Add v2.0 (Q1 2026) "Editor Launch Sprint" with three pivotal entries: Polyfill Layer (6 Electron-to-Tauri polyfills), ESBuild Configuration Framework (12 exclusion pattern modules), and Source Compilation Migration
- Document two-stage compilation pipeline architecture: TypeScript → ESBuild config → bundling
- Expand v1.x entries with specific version numbers, dates, and file counts
- Add initial v0.2 (Q4 2024) founding entry with first artifact batch details

This restructuring provides comprehensive historical context for the Output component's evolution from initial artifact generation through current Tauri integration.
