fix: parse Claude Fable current-week usage

Claude Code 2.1.199 renders the Fable plan bucket as Current week (Fable), while Orca only parsed a standalone Fable heading. Accept weekly-style Fable headings as the distinct Fable weekly meter while keeping broader Fable-weekly copy as a section boundary to avoid false positives.
