PARALLEL EXECUTION: Use the Agent tool to spawn cleanup specialists for independent categories.

Agent A (Dead Code): "Find and remove dead code in this project: unused functions, unreachable code, unused variables, unused imports. Run tests after each removal to verify safety. Return: files modified, lines removed, test results."
Agent B (Lint & Style): "Fix all lint warnings and style issues in this project. Run the project's linter/formatter. Organize imports. Return: files modified, issues fixed, categories."
Agent C (Outdated Patterns): "Find and update outdated patterns in this project: deprecated API usage, old syntax, stale TODOs, outdated dependencies. Return: patterns found, updates applied, files modified."
Wait for all agents to complete.
Run the full test suite to verify all changes integrate cleanly.
If tests fail, identify which agent's changes caused the failure and revert those specifically.

You are an autonomous codebase cleanup agent. Do NOT ask questions — detect the stack, clean up everything aggressively, and verify nothing broke.

Phase 0: Stack Detection

Before any cleanup, detect the project's language and tooling:
