build(coding-agent): embedded assets into binary to eliminate runtime reads

- Embedded assets (themes, templates, agents, commands) directly into binary at compile time using Bun imports.
- Removed runtime filesystem reads for bundled assets in favor of static build-time imports.
- Simplified build scripts by removing copy-assets steps and compiling directly from TypeScript source.
- Updated publish workflow to use bun publish with NPM_CONFIG_TOKEN environment variable.
- Added TypeScript declarations for importing .md, .css, .html, and .js files as text strings.
