Add TypeScript type definitions for package exports

[Copilot]

Plan: Add TypeScript type definitions for exports

• Understand repository structure and exports
• Create type definitions for ./jest export (jest.d.ts)
  • Re-export types from @jest/globals
• Create type definitions for ./expect export (expect.d.ts)
  • Re-export types from expect package
• Create type definitions for ./node export (node.d.ts)
  • Re-export types from node:test module (@types/node)
• Create type definitions for ./mock export (mock.d.ts)
  • Custom types for Exodus-specific APIs
• Create type definitions for ./tape export (tape.d.ts)
  • Custom types for tape-compatible API
• Create type definitions for ./benchmark export (benchmark.d.ts)
  • Custom types for benchmark API
• Update package.json to reference type definitions in exports
• Update tsconfig.json paths to point to .d.ts files
• Test TypeScript integration with type checking
• Fix type definitions to use declare keyword for esbuild compatibility
• Run linter and format code with prettier
• Address code review feedback
• Remove package-lock.json and add to .gitignore (repo uses pnpm)

Key Changes

This PR adds TypeScript type definitions for all package exports by re-exporting from official type packages wherever possible, following the "borrow from jest, node, etc" approach suggested in the issue.

Type Definitions Added

All type definition files now leverage official type definitions from the ecosystem:

• expect.d.ts (11 lines): Re-exports types from the expect package (existing optionalDependency)
• jest.d.ts (28 lines): Re-exports types from @jest/globals (existing devDependency)
• node.d.ts (28 lines): Re-exports types from node:test module (@types/node)
• mock.d.ts (49 lines): Custom types for Exodus-specific utilities (fetchReplay, websocketRecord, timersSpeedup, etc.)
• tape.d.ts (154 lines): Custom types for tape-compatible API
• benchmark.d.ts (35 lines): Custom types for benchmark API

Benefits

• Reduced maintenance burden: By re-exporting from official packages (expect, @jest/globals, node:test), we avoid maintaining duplicate type definitions
• Better type accuracy: Official type definitions are maintained by their respective package maintainers
• Smaller codebase: Total reduction of ~450 lines by leveraging existing types

Only mock.d.ts, tape.d.ts, and benchmark.d.ts contain custom type definitions for library-specific APIs that don't exist in standard packages.

Removed package-lock.json and added it to .gitignore in commit 7282e61.

@copilot put under node_modules

[Copilot]

Done in commit 8f8c25b. Moved package-lock.json entry under node_modules in .gitignore.

@copilot can we re-export types/node?

[Copilot]

Done in commit 8f8c25b. The node.d.ts now re-exports types from the node:test module (@types/node), reducing the file from 150+ lines to 28 lines.

Pull request overview

This PR adds TypeScript type definitions for all package exports, enabling better IDE support and type checking for consumers of the @exodus/test package. The approach leverages official type definitions from ecosystem packages where possible (expect, @jest/globals, node:test) and provides custom types for library-specific APIs.

Changes:

• Added 6 new .d.ts type definition files covering all package exports (jest, node, tape, expect, mock, benchmark)
• Updated package.json exports to reference type definitions using the "types" field
• Updated tsconfig.json paths to point to the new type definition files
• Added package-lock.json to .gitignore (appropriate since repo uses pnpm)
