chore(ci): upgrade labeler action to v6 and add base-branch labels

Updated GitHub labeler from v4 to v6 to support the new configuration
format and base-branch matching capabilities. Migrated all existing
file-based label rules to the v6 format using changed-files syntax.

Added core2 and core3 labels that automatically apply based on PR
target branch (main and vincent-and-the-doctor respectively) using
the new base-branch matching feature.
