Analyze this codebase to generate or update .github/copilot-instructions.md for guiding AI coding agents.

Focus on discovering the essential knowledge that would help an AI agents be immediately productive in this codebase. Consider aspects like:

• The "big picture" architecture that requires reading multiple files to understand - major components, service boundaries, data flows, and the "why" behind structural decisions
• Critical developer workflows (builds, tests, debugging) especially commands that aren't obvious from file inspection alone
• Project-specific conventions and patterns that differ from common practices
• Integration points, external dependencies, and cross-component communication patterns

Source existing AI conventions from **/{.github/copilot-instructions.md,AGENT.md,AGENTS.md,CLAUDE.md,.cursorrules,.windsurfrules,.clinerules,.cursor/rules/**,.windsurf/rules/**,.clinerules/**,README.md} (do one glob search).

Guidelines (read more at https://aka.ms/vscode-instructions-docs):

• If .github/copilot-instructions.md exists, merge intelligently - preserve valuable content while updating outdated sections
• Write concise, actionable instructions (~20-50 lines) using markdown structure
• Include specific examples from the codebase when describing patterns
• Avoid generic advice ("write tests", "handle errors") - focus on THIS project's specific approaches
• Document only discoverable patterns, not aspirational practices
• Reference key files/directories that exemplify important patterns

Update .github/copilot-instructions.md for the user, then ask for feedback on any unclear or incomplete sections to iterate.
