Cardano Updates

Replace bracket-based cleanup with explicit error handling to fix
issue where workspace directories were removed even when tests
failed, making debugging difficult.

Changes:
- Replace bracket with catchAssertion in workspaceWithConfig
- Preserve workspace directories when tests fail for debugging
- Clean up directories only on successful test completion
- Add MonadAssertion constraint to workspace functions
- Update WorkspaceSpec test to verify correct behavior

Fixes #95

Add comprehensive workspace behavior tests to document and verify
current workspace cleanup behavior. Extend the Base module with
workspaceWithConfig function providing explicit control over
workspace cleanup operations.

Changes:
- Add WorkspaceSpec test module with tests for workspace cleanup
  on success, failure, and with keepWorkspace flag
- Extend Base module with workspaceWithConfig for cleanup control
- Update cabal file to include new test module

The new tests provide foundation for future improvements to
workspace management functionality.

Add missing directory package dependency to hedgehog-extras-test
suite required by the new WorkspaceSpec test module for filesystem
operations.

Add three new command templates to integrate Claude IDE with git
workflows and omni-dev toolchain for enhanced developer
productivity.

Commands added:
- commit-twiddle: automated commit message improvement using
  omni-dev
- pr-create: automated pull request creation with template support
- pr-update: automated pull request updates based on branch
  changes

Also update .gitignore to exclude Claude IDE local settings files
to prevent accidentally committing user-specific configurations.

Add three new command templates for Claude IDE integration:
- commit-twiddle: automated commit message improvement using omni-dev
- pr-create: automated pull request creation with template support
- pr-update: automated pull request updates based on branch changes

These templates provide structured workflows for common git operations
and integrate with the omni-dev toolchain for enhanced developer
productivity.
