Codebase Deep Clean

Dispatch 8 subagents to audit and clean the codebase. Each subagent must: (1) research its domain, (2) write a critical assessment with findings, (3) implement all high-confidence fixes.

Pre-flight

• Detect project language(s) from config files (package.json, Cargo.toml, pyproject.toml, go.mod, etc.) and tailor subagent instructions accordingly.
• Identify the test runner and verify tests pass before starting. Abort if tests are already broken.
• Create a working branch: cleanup/<YYYY-MM-DD>.
• Exclude generated files, node_modules, dist, vendor, lock files, and any paths listed in .gitignore.

Execution order

Some subagents have dependencies. Run in two phases:

Phase 1 (parallel): 1, 2, 5, 6, 7, 8 Phase 2 (parallel, after Phase 1 commits): 3, 4
