Add CI pipeline

[n-hallberg]

• Introduced .prettierrc and .prettierignore for code formatting.
• Added cspell.json for spell checking configuration.
• Created eslint.config.mjs for linting rules.
• Set up GitHub Actions CI workflow for automated checks (linting, type checking, testing).
• Added minimal fixture for E2E testing with Convex.
• Included various utility scripts and configurations for testing and development.

Greptile Summary

This PR establishes a comprehensive CI/CD infrastructure for the convex-e2e testing library. It introduces automated quality checks (linting, type checking, formatting, spell checking) and a complete unit test suite achieving good coverage of the existing codebase. The E2E fixture provides a working example demonstrating how to use the library with a minimal Convex backend.

Key additions:

• GitHub Actions workflow with two jobs: ci (quality checks and unit tests) and e2e (integration testing with fixtures)
• Configuration files for ESLint, Prettier, and cspell with sensible defaults
• Comprehensive unit tests for assertions, client, runner, reporter, and convex-run modules
• Minimal E2E fixture with Convex backend, test suites, and helper functions
• Exported previously internal functions (parseConvexOutput, filterSuites, parseError) to enable testing

Minor issue:

• fixtures/minimal/convex/testSupport.ts:103 - table parameter is destructured but never used

Confidence Score: 5/5

• This PR is safe to merge with minimal risk
• The PR adds infrastructure code (CI, tests, config files) without modifying core business logic. All changes are well-structured, follow best practices, and include comprehensive test coverage. The only issue is a minor unused parameter that doesn't affect functionality.
• No files require special attention
