fix(workflow): resolve type errors across all packages and remove tsbuildinfo from tracking

- Add bun-types and @types/xxhashjs to root devDependencies
- Add types: ['bun-types'] to root and package tsconfigs
- Fix AST Node type narrowing in bundle-validator.ts with AcornNode type and narrowNode helper
- Fix generic ThreadContext variance in create-role-moderator.ts
- Add explicit parameter types in worker.ts
- Fix ChildProcess type in worker-spawn.ts to match spawn() stdio config
- Remove all tsconfig.tsbuildinfo from git tracking
- Add tsconfig.tsbuildinfo to .gitignore
