Optimize Docker build caching and slim image

- Add pnpm store cache mount so package reuse survives layer invalidation
- Copy only prisma schema files (not migrations/programmability/seed) into deps
- Remove prisma and scripts from runner stage (no longer running migrations in container)
- Expand .dockerignore to exclude docs, tests, .claude, .github, .vscode (~30MB less context)
