Add .claude/skills/monthly-review: a Claude Code skill that builds a
higher-level monthly timesheet review by synthesizing the weekly review
sections of the month's week notes, and writes it as a note in
Work / Self-Reviews.
Uses a strict calendar-month day filter (straddling weeks count only for
their in-month days), the weekly review sections as the source of truth,
and the CLI only for per-week totals. The review has a month-level
narrative (shape, major threads, recurring work) plus an inspections
section: time allocation, stuck/recurring threads, and long weeks (a
low-logged week is treated as unlogged leave, not reduced output).
