fix merge conflicts to prep for merge with branch next

- Enhance E2E testing and LLM analysis report and:
  - Add --analyze-log flag to run_e2e.sh to re-run LLM analysis on existing logs.
  - Add test:e2e and analyze-log scripts to package.json for easier execution.

- Correct display errors and dependency validation output:
  - Update chalk usage in add-task.js to use bracket notation (chalk[color]) compatible with v5, resolving 'chalk.keyword is not a function' error.
  - Modify fix-dependencies command output to show red failure box with issue count instead of green success box when validation fails.

- Refactor interactive model setup:
  - Verify inclusion of 'No change' option during interactive model setup flow (task-master models --setup).

- Update model definitions:
  - Add max_tokens field for gpt-4o in supported-models.json.

- Remove unused scripts:
  - Delete prepare-package.js and rule-transformer.test.js.
