Add branching-strategy skill with next and create actions

Version-aware branch naming (X.Y.Z.Q/{TASK_CODE}-{FEATURE}-{SEQ}),
branch creation from origin/test with origin/main fallback, and the
PR-into-test merge rule. Ships a TypeScript CLI (next, create) plus
shell modules (loggers, base, cli) run via Taskfile.
