docs: sync routing after merge

Reflect the /close → /capitalize --ritual merge in the session-loaded routing
table (CLAUDE.md) and the README/USAGE command tables: capitalize now also
reconciles .claude/tasks/TODO.md, --ritual adds the end-of-session reflection,
and /close is documented as an alias. Does not touch the in-progress caveman
purge edits in these files (left unstaged).
