🤖 Prompt for all review comments with AI agents

Verify each finding against current code. Fix only still-valid issues, skip the
rest with a brief reason, keep changes minimal, and validate.

Inline comments:
In `@cubic.yaml`:
- Around line 20-21: Remove the unsupported
auto_approve_rules.exclude_external_contributors setting from the configuration
and leave auto_approve_rules limited to its valid include/exclude glob paths.
The external contributor behavior is already handled by
external_contributors_require_manual_review, so update the cubic configuration
to use that existing setting and keep the auto_approve_rules section valid.

[cubic-dev-ai]

I've successfully fixed both issues in cubic.yaml:

Issue 1: Fixed glob patterns for Draft/WIP PR titles (cubic.yaml:30-31)

Changed "[Draft]*" and "[WIP]*" to "Draft*" and "WIP*". The brackets were creating character classes that matched any title starting with D/r/a/f/t or W/I/P (e.g., "fix", "refactor", "add" would all be ignored). The corrected patterns now properly match titles starting with "Draft" or "WIP" as intended.

Issue 2: Added missing trailing newline (cubic.yaml:41)

Added a trailing newline at the end of the file to match the repo's Prettier formatting expectations.

✅ All tests passing (232 tests passed)

The changes ensure that the ignore patterns work correctly and the config file follows the proper formatting standards.
