docs: clean up redundant Copilot instructions

[Copilot]

The .github/copilot-instructions.md file contained setup instructions that duplicated the automated setup already provided by copilot-setup-steps.yml. This created confusion and unnecessary maintenance overhead.

Changes Made

Removed redundant setup sections:

• Eliminated manual environment setup instructions (Python, uv, pre-commit, pyright installation)
• Removed the entire "Copilot Agent Environment Setup" section that duplicated automated setup
• Simplified the "Bootstrap, Build, and Test" section to focus on usage rather than setup

Updated documentation to reflect automated setup:

• Modified environment setup instructions to simply reference activating the pre-configured virtual environment
• Updated troubleshooting section to reflect that tools are pre-installed
• Revised development notes to mention the pre-configured environment

Preserved essential information:

• Kept all usage instructions for running tests, linting, type checking, and building documentation
• Maintained CLI usage examples and validation steps
• Preserved timing information and troubleshooting guidance

Impact

The instructions now accurately reflect that the Copilot environment automatically sets up all necessary tools, eliminating redundancy while maintaining all essential information for developers. This reduces confusion and ensures the documentation stays in sync with the automated setup process.

Fixes #539.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• docs.deepmodeling.com
  • Triggering command: /home/REDACTED/work/dpdispatcher/dpdispatcher/.venv/bin/python3 /home/REDACTED/work/dpdispatcher/dpdispatcher/.venv/bin/sphinx-build -M html . _build (dns block)
• docs.python.org
  • Triggering command: /home/REDACTED/work/dpdispatcher/dpdispatcher/.venv/bin/python3 /home/REDACTED/work/dpdispatcher/dpdispatcher/.venv/bin/sphinx-build -M html . _build (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

💡 You can make Copilot smarter by setting up custom instructions, customizing its development environment and configuring Model Context Protocol (MCP) servers. Learn more Copilot coding agent tips in the docs.
