fix(cli): fix branch-specific item filtering to check if type is configured

The previous logic incorrectly skipped branch-specific files when:
- specificItems was configured but didn't include the item type
- e.g., folders: ["f/**"] in config, but a folder.dev.meta.yaml file
  would be skipped because isSpecificItem returned false

New logic with isItemTypeConfigured:
- If item type is NOT configured in specificItems -> process normally
- If item type IS configured but doesn't match pattern -> skip
- If item type IS configured and matches pattern -> process

Added tests for:
- isItemTypeConfigured function
- Filtering behavior with different config combinations
- getSpecificItemsForCurrentBranch with branch override
