fix: Improve production deployment configuration (#155)

* fix: Improve production deployment configuration

- Update default port from 3003 to 3002 for consistency
- Make port configurable via environment variable in docker-compose
- Add .env file loading support in start-api.sh
- Optimize startup.sh for production (skip builds, expect pre-built dist)
- Make Claude Code image build conditional on Dockerfile availability
- Fix rate limiting configuration for proxy environments
- Remove jest types from tsconfig (not needed in production)

These changes improve deployment flexibility and production readiness.

* fix: Address PR review feedback

- Fix port inconsistency: Change hardcoded 3003 to 3002 in src/index.ts
- Fix security risk: Replace unsafe export command with set -a/source/set +a
- Remove unnecessary Dockerfile.claudecode volume mount from docker-compose
  (The Dockerfile already copies all necessary files during build)

These changes address all critical issues identified in the PR review.
