Loops — recurring maintenance disciplines that keep the repo legible over time

A new context-v category for skills that aren't one-shot specs or plans but **recurring rhythms** — the small, regular maintenance moves that keep a fast-moving repo readable to humans + agents who weren't there when the work happened. Each loop lives as its own subdirectory with a SKILL.md, optional scripts/, and templates/. Companion concept (TBD): `context-v/pairing/` for human-agent collaboration disciplines.
