fix: massive linting cleanup with 3-agent swarm

- Fixed browser globals with /* eslint-env browser */ (28 files)
- Fixed Node.js globals with /* eslint-env node */ (9 files)
- Converted require() to ES imports (7 files)
- Fixed 165 TypeScript any types with proper types
- Fixed unused variables by prefixing with _ or removing
- Fixed case declarations by adding block scope
- Total files modified: 57

Linting issues reduced from 3,964 to 3,088 (876 fixed, 22% improvement)
Overall reduction: 6,884 → 3,088 (55% total improvement)
