## Description
<!-- SECTION:DESCRIPTION:BEGIN -->
Currently renderer.ts is a single file loaded directly by Electron's renderer process via a script tag in index.html. To split it into modules (TASK-6), we need a bundling step since Electron renderer's default context doesn't support bare ES module imports without additional configuration.
Options:
1. **esbuild** — fast, minimal config, already used in many Electron projects
2. **Electron's native ESM support** — requires `"type": "module"` and sandbox configuration
3. **TypeScript compiler output** — if targeting a single concatenated bundle
The build pipeline already compiles TypeScript and copies renderer assets. Adding a bundling step for the renderer would slot into the existing `npm run build` script.

## Acceptance Criteria
<!-- AC:BEGIN -->
- [ ] #1 Renderer code can be split across multiple .ts files with imports
- [ ] #2 Build pipeline bundles renderer modules into a single output for Electron
- [ ] #3 Existing `make build` still works end-to-end
- [ ] #4 No runtime errors in renderer process
