v0.8.0

Provider-neutral backlogs. Backlog items no longer bind to Claude by default, and
a new loop flag lets a Claude-aliased backlog run portably under any agent without
editing it — closing the #38 failure mode where a model: "opus" item silently
halted the loop under a non-Claude agent. Additive minor bump.

Added

• rauf loop run --no-model (alias --model none) — ephemeral per-run model
  override that makes the loop ignore each backlog item's model field for that
  run (the new ignoreItemModel loop option). Resolution drops to
  --model > project default > provider default, so a backlog whose items carry
  Claude-only tier aliases (opus/sonnet/…) runs portably under a non-Claude
  --agent without a persistent edit to backlog.json. Also accepted on the
  POST /loop/start body for server-mode parity. (#38)

Changed

• author-backlog skill is provider-neutral by default — item model is now
  omitted unless the user explicitly opts into a Claude tier, keeping authored
  backlogs agent-portable. Tier aliases are documented as Claude-only and
  agent-binding. (#38)
• review-backlog skill flags items carrying Claude-only model aliases as a
  portability concern (new "Claude-bound model alias" anti-pattern). (#38)
