fix: include changelog in docker web build

[pandego]

Summary

• fix the Docker web build by including CHANGELOG.md in the frontend build context
• stop excluding CHANGELOG.md from the Docker build context in .dockerignore

Problem

docker compose up --build -d was failing on current main during the frontend build.

The Vite changelog plugin reads CHANGELOG.md at build time, but the Dockerfile only copied package.json, bun.lock, app/, and web/ into the frontend stage. The build then failed with:

[changelog] Could not load virtual:changelog ... ENOENT: no such file or directory, open '/build/CHANGELOG.md'

Fix

• copy CHANGELOG.md into the frontend Docker build stage
• remove CHANGELOG.md from .dockerignore so it is actually available to Docker

Validation

• reproduced the failure locally on a fresh branch from latest main
• ran docker compose up --build -d
• confirmed the container reaches healthy state on 127.0.0.1:17493
• confirmed GET /health returns healthy JSON
• opened http://127.0.0.1:17493/ in the browser and verified the Voicebox UI loads

Closes #308.

Summary by CodeRabbit

• Chores
  • Updated Docker build configuration to include the CHANGELOG file in the Docker image, making it available within the containerized application.

Poem

🐰 A changelog joins the Docker spree,
No longer hidden, now all can see,
Built with the bundle, locked and tight,
The frontend now compiles just right! 📦✨
